Antares is getting RD-181Ms. What do we know about them?
The only thing I'm sure of is that they use only Russian components.
Export version of RD-191M which has design changes and uprated thrust and other specs to address underperformance on the Angara family of launchers and other launchers. AFAIU, NG hasn't settled officially on which engine it might select. The second stage is also a focus of other proposed upgrades path options. NG is keeping everything under wraps but has been communicating with NASA regarding CRS3 programme formulation. There are slightly further details in L2 but beyond that it is to early to assume in detail at this stage. Energomash did the presser regarding what they would offer which tipped everyone off regarding NG Antares upgrades RFI, which is an early step in the formal evaluation and selection (tendering) process which can result in contract(s) being awarded that meet NG's vehicle performance and other upgrade target metrics.

Does anyone know what propellant the Antares second stage uses in its reaction control system? Hydrazine or cold gas?

Cold gas, per the Antares User's Guide:

According to Twitter reports, Yuzhnoye & Yuzhmash in the Ukraine have been completely destroyed in the Ukraine war (official confirmation pending). So if this is confirmed, further production of Antares rockets won't be possible.

During the NG-17 pre-launch press conference, Northrop Grumman said that it had all the launch hardware it needed to complete NG-18 and NG-19, completing the CRS-2 contract. It is bidding for CRS-3, was going to bid an improved Antares still with Russian engines as far as I know, but will obviously now have to bid an alternate launch vehicle.

SpaceNews: "This has not been confirmed. A Ukrainian space official told SpaceNews on Feb. 25 that the Yuzhmash factory has not been damaged."
I think this is Jeff Foust speaking.

Even assuming that the reports are true...is there any truth to what Jonathan McDowell says?

Yuzhnoye has there presently shuttered Americas/Pacific headquarters in Reston, VA and they have there EU/AU headquarters in Wezembeek-Oppem, Belgium.

The Boeing Rocketdyne RS-84 is the cancelled AR-1 predecessor from the SLI programme.

There was one or so at the last launch

I know that the first launch of the Antares 330 is scheduled for June 2025 and that three Antares 330 launches are currently on Northrop Grumman's launch manifest. In your opinion, will the Antares 300 series have a launch frequency exceeding that of the Antares 200 series?

Why does every one of your posts look like something a chat bot came up with?
Probably because it did. I'm convinced this poster is either a real person posting AI generated content or is a not a real person's account that perhaps some sort of an experiment. Very unusual posting behaviour and AI sounding language.
I wanted to have users give their opinion on whether or not the launch frequency of the Antares 300 series will rival or exceed that of the Antares 200 series now that the Antares 200 series is now retired because the first stage of the Antares 300 series will use the Miranda engines that also will power the Firefly Aerospace MLV, and the forthcoming cargo version of the Dream Chaser spaceplane will create not two, but three companies supplying freight to the ISS under the CRS program.

Antares flight rate has nothing with the type of first stage. It is driven by ISS demand and contracts.

I suspect the question being asked is whether Antaras will get any other non ISS customers
