TLEs out for three payloads and the Briz-M - nothing yet for a putative 4th payload.
Briz-M in 1170 x 1504 km disposal orbit, rest in 1494 x 1506 km, so looks like mission success for the Gonets and Briz.
I recall that Kosmos-2499 took a while to be discovered and cataloged.

Was the second special payload given a Kosmos designation?

A fifth object has been catalogued in an orbit close to that of object D (could be Kosmos-2504 in an orbit close to that of Briz-KM)
2015-020E/40556 in 1172 x 1506 km x 82.49°

The object currently classified as 40555/2015-020D is transmitting at the same radio frequency as COSMOS-2491 and COSMOS-2499. It is highly likely that 40555/2015-020D is COSMOS-2504.

Kosmos-2504 has begun manuevers in orbit.
On Apr 9 the orbit was raised by about 3 km. Further changes continued on Apr 13-14.

There appears to have been a rendezvous between Kosmos-2504 and the Briz-KM upper stage around April 16, with the Briz-KM eventually ending up in a higher orbit.

Here's an update on the website of Anatoly Zak, who speculates there may have been some kind of physical contact between the two objects.

Kosmos-2504 is article 14Ф153?

As noted by Anatoliy and Igor in other forums, Kosmos-2504 made a major orbit change on Jul 3.

On Jul 3 around 0710 orbit changed from 1172 x 1506 km to 1117 x 1455 km
Later on Jul 3 this was tweaked to 1119 x 1452 km  (or,  might be just a more accurate measurement)

The Briz-KM stage is still in a 1172 x 1506 km orbit, no change since the Apr 14 orbit perturbation noted by Anatoliy.

From 30 Mar 2017 till 20 Apr 2017 K2504 has descended in several paces by 500 km in perigee height.
