From what I can tell from these, it looks like the heroes in the top two pictures are stormer (or bulk), breez, and nex. Next two pictures have surge and rocka, (of course we all know that). The interesting thing is that the rocks in those two appear to be floating, as if something is messing with the gravity. The third one from the bottom is a bit hard to see up close, but I think the heroes in that one are bulk, stringer, and evo. No other signs of furno though, ever since he got dragged away by splitter beast's little brother......
