I believe the top rightmost figures with the umbrella and yellow patterned coat, respectively, are the main characters from the Kingsmen movies. And correct me if I'm wrong: I think the fellow with a towel over his head (directly above Rocket Raccoon) is Arthur Dent from Hitchhiker's Guide to the Galaxy.
Filled the note but I couldn't find Black Widow and Sly Cooper. Are they really in the post?
