All three appear to be Terrier Malemutes (not improved Malemutes). The fins used on the improved Malemutes (in fact demilitarized Patriot motors) are different. Also improved Malemutes appear to have bright red motor cases, while Malemutes were mostly dark.

"Japan Aerospace Exploration Agency (JAXA) launched the SS-520-3 Sounding Rocket aimed at "research of the plasma outflow phenomena in the cusp region" from Andøya Space Center, Svalbard Rocket Range (Norway) on Thursday Nov. 4.
After the successful launch and flight, SS-520-3 dropped onto South-southwest ocean of Svalbard Rocket Range."

I emailed Andøya Space regarding the recent the recent PMWE sounding rocket launches. they replied with
"The rocket motors were Improved Malemute motors."
In addition, we have this:
https://twitter.com/planet4589/status/1456509378241220608The T-Minus folks implied to me that only one of the Andoya launches was theirs.
Here,
https://www.blv.no/nyheter/sender-ni-raketter-etter-ekko/ we have
"The research project is about launching two larger and seven smaller rockets. The two large rockets are sent up to an altitude of 125 kilometers, and are salvaged from the sea again afterwards, so that they can be reused again later."
Given this, the smaller rockets were likely the T-Minus Darts, and the two larger ones Improved Malemutes.

Cross-post, about the recent launches in Andøya:
From T-Minus Engineering on LinkedIn:
On the 3th of October at Andøya Space Norway, T-Minus Engineering launched a T-Minus DART rocket.
With an efficient buildup and preparation, the rocket motor ignited perfectly and the vehicle accelerated out of the tower to the supersonic regime. At high supersonic speed, an instability occurred and the vehicle was unable to deploy a qualification payload engineered by T-Minus Engineering. The reason for this anomaly is currently under investigation.
Overall we look back at a successful test campaign and collaboration, and we are one step closer to a fully successful flight.
We thank the staff of Andøya Space and DLR Moraba for their support during the campaign.
T-Minus launched 1 Dart but it seems unrelated to the PMWE mission according to what they say about the payload ("was unable to deploy a qualification payload engineered by T-Minus Engineering") and it could be the one that Jonathan McDowell mentioned earlier in his tweet. But what about the other launches? Could it be that the 7 "smaller" rockets were not T-Minus Darts?

In that case, where the "smaller" rockets IM's and the "larger" rocket IM IM's? Would fit with the email I received. That commonality would make sense. That would be 7 Improved Malemute's and 2 Improved Malemute Improved Malemute's.

That seems reasonable, I'll tentatively adopt that.

AFAIK they only launched three rockets during the PMWE compaign.
The two PMWE rockets with Improved Malemute motors.
And the T-minus Dart, that had instability problems. They couldn't use the probe (Rexus Prime FFU, I guess).
Because the probe couldn't deploy from the dart, the experiments failed to take measurements. Thus they didn't launch the other six T-minus Darts. T-Minus Engineering has some redesign work to do on the fins of the darts.
I think T-minus require some help from DLR MoRaBa, for stability is transonic regime.
I really like this test:

An Oriole-IV sounding rocket was launched from Andøya at 09:25 UT on December 1, carrying the C-Rex 2 payload (49.004 UE), and reached an altitude of 634 km.
NASA’s Cusp Region Experiment-2, also known as CREX-2, was the final research rocket to launch in the international project Grand Challenge Initiative Project Cusp.
The project consisted of 12 rockets from three nations: USA, Norway, and Japan. The main objective of the project was to investigate the polar cusp region, a region formed by Earth’s magnetic field. The magnetic field forms a kind of a funnel stretching from our atmosphere down towards Earth’s core, and inside this funnel the air is noticeable denser than elsewhere, says Kolbjørn. This affects polar orbiting satellites, as they hit a kind of speed bump when they pass through this area.
CREX-2 was led by Professor Mark Conde from the University of Alaska Fairbanks, and the vehicle was built at NASA Wallops.
The rocket carried 20 canisters of vapor tracers which was released into the atmosphere, says Kolbjørn. Each of these canisters created a small cloud which was then observed by two ground stations at Svalbard and by an airplane flying out from Iceland.

There's going to be suborbital launch from Woomera during the period 21 March 2022 to 10 April 2022, when Amber Zone 2, the launch corridor from Woomera, will be out of bounds.
https://www.defence.gov.au/bases-locations/sa/woomera/access/exclusion-periodsAmber Zone 2 was also closed from 4 October to 7 November last year. I suspect these launches are related to hypersonics research, that went black after HIFiRE 4 in 2017.

DXL Sounding Rocket Launch
A two-stage Black Brant IX suborbital sounding rocket is scheduled for launch Jan. 8, 2022, carrying the Diffuse X-rays from the Local galaxy, or DXL, an experiment to study the source of where soft X-rays that impact Earth’s atmosphere come from within our galaxy.
The launch window opens 11 p.m.-3a.m. EST. Backup launch days run through Jan. 17 with the same launch window. The live stream will begin 20 minutes before the planned launch time.

https://twitter.com/NASA_Wallops/status/1480041842460835842LIFTOFF ❗ A Black Brant IX sounding rocket carrying the DXL mission launched at 12 a.m. ET. The mission will study the origin of soft x-rays in our galaxy that impact technology in Earth’s atmosphere.

About the mission:
NASA January Launch Studying Sources of Space X-raysX-rays from space bombard Earth on a daily basis. The sources and characteristics of these X-rays are not clearly understood.
A January 2022 NASA sounding rocket mission called the Diffuse X-rays from the Local galaxy, or DXL, hopes to shed light on the sources of soft X-rays that hurtle towards Earth from elsewhere in our galaxy.
<snip>
While not harmful to humans on Earth, soft X-rays can make changes in the Earth’s ionosphere which can disturb radio communications and the accuracy of GPS navigation systems. They have lower energy as compared to hard X-rays, which are used in imaging for medical applications.
“Very low energy diffuse X-rays from space are believed to come from two sources,” said Massimiliano Galeazzi, the principal investigator for the DXL mission from the University of Miami, Florida. “The first source is located outside our solar system and is generated by remnants of multiple supernovae explosions forming what is now called the Local Hot Bubble region of our galaxy. The second source is within the solar system and is generated by the solar wind charge exchange. DXL seeks to gain a better understanding of the nature and characteristics of these sources.”
This will be the fourth flight of DXL. The first flight in 2012 confirmed the Local Hot Bubble as a source of these X-rays. Data from the flight indicated that only about 40 percent of the soft X-ray background originates within the solar system, which means the LHB is the dominant source.
