I vote for Maximum Fire, Bouncer Rabbit and Episode 3 (GO).

Basicly the entire bottom row.

As for the title I think its got something to do with stages.

I'm not sure where to go on but I'm sure the pictures have something to do with 1 + 2 = 3.

If not Stages then the pictures most likly add within them selves to make something else like 1 add 2 making 3 the same would be one picture adding another makes another picture.
