Reynolds is worth 25 bonus shots. 975 is tricky. Olsky from Punisher's surname is apparently unrevealed. There is a Roy Olsky but he appears in Daredevil rather than Punisher. They might be the same character because they both work in corrections but this has not been confirmed. I meant to grab the Punisher version but it looks like I accidentally grabbed the Daredevil version. Regardless I'll count that as correct along with the others. Because I used Roy in the image, if the other Olsky does appear in a later collage, I'll make sure I use the Punisher image.

 

Cleaned up clues:

For characters not from commercials who first appeared in the 00s-20s I'm indicating Yes, No, or Partial to if they're from the MCU. For purposes of this collage series (not just this round), a character is Partial if they're from an alternate universe from the MCU perspective (Spider-Man 2002 or Amazing Spider-Man 2012 universes weren't originally quasi-MCU so they're treated as No); or they're from the Framwork, the Dark Dimension, a D'Spayre vision, the Healing Algorithm, Duat, or pretty much any reality seen in Loki. Since the Chronicoms originated in the main MCU reality, they're listed as Yes even if only seen in the alternate reality.

1084 Fortner, Jessica Jones

1251 Frank Delacourt or Tobias Ford (I don't think it's ever been established which one is which in the single image that shows both), AoS

1123 Tom Benson (Monolith recreation), AoS

1094 Tomas Cianco, Luke Cage

1035 Kebo, AoS

For 1251 it's definitely not Tobias Ford, who's an active participant in that episode.  I'm going with https://aveleyman.fandom.com/wiki/Agents_of_S.H.I.E.L.D._S01E09_%22Repairs%22 says, which is a character other than Frank Delacourt,  though I don't know how they determined which is which. I agree it's ambiguus though, so had you mentioned the other character I probably would have given this to you.

The rest are correct; list updated.

 

1251 Jack Benson, AoS
