Bellona says that Russia ever produced 248 nuke subs, 196 of which have been decommissioned. So, 52 left in commission, my guess:

4 Typhoons, incl. TK 13 in reserve. TK 17, 20 and 208 are operable
6 Delta IV, K 64 scrapped in 2001-2, K 117 and 18 in repair.
7-8 Delta III, incl. K 490 Voskresensk in reserve. K44 Ryazan in repair.
10 Oscar IIs, only 5 operable, K132, 119, 442, 266 and 526.
13 Akulas, K 284 Puma retired in 1995. K263, 322, 480, and 391 in reserve
3 Sierras, K 239 Karp retired in 1998, only K 276 active, rest in repair
5 Victor IIIs, incl. B 292 Perm in repair
