I recently got a huge bag of LEGO's. I figured out what some of them were, but there were still these left over, and I couldn't find anything about them.
The parts on the left of the top photo are from 76020-1: Knowhere Escape Mission
the part on the right of the top photo is 30156pb02 : Panel 4 x 6 x 6 Sloped with Stone Wall Pattern
based on the windows it should come from 7785-1: Arkham Asylum
The bottom one is part of 6873-1: Spider-Man's Doc Ock Ambush
You can see the distinctive riser on the left.
