2c - next to the circle, it's the glass container where the facehugger has been stored (Aliens)

0 - behind Akira - it looks a bit like Alien mother's legs or something like that

are the colored portals identified? (0f, 9e)

the skeleton on the right ... was not there st. like that in Simpson's Halloween Special?

Unknown humanoid in 0e looks like a Combine soldier to me

I wonder if the red object on the very top might be a sword from the Soul Calibur series?

0f 9e portals look like portals from Portal game (and both are next to some other Portal references). They should be probably added to the list.

Black guy standing in front of counter in 2d is almost certainly Carl "C.J" Johnson from GTA San Andreas: vignette.wikia.nocookie.net/gtawiki/images/6/63/…

On a second look, it's not the glass container from Aliens, but a cat transport box, clearly for the facehugger. Heh :)

"7[c] unknown humanoid boxing Prawn alien" could be the pig boxer from the game Beast Boxing Turbo (screenshot: cdn.edgecast.steamstatic.com/steam/apps/259490/…)
