Gamera is the green turtle, the one that has the propulsion coming out the legs in another photo.

The turtle thing with ears and in brown is Baragon.

The batwinged creature is a bad guy from Gamera called Gyaos

Gamera and Gyaos are from the First movie (Gamera: Guardian of the universe) of the gamera trilogy during the revival in the 90s (but were around long before that, just these designs specificly allude to that movie). Baragon is a random Kaiju (japanese monster) from Godzilla and Gamera stuff. Japan tends to reuse monster suits when they can, to save on cost.

I was really hoping those little green army men would be articulated. Oh well

I just re-watched Toy Story 1 + 2 on Blu-Ray a few days ago. And I don't recall Buzz being that short compared to Woody?? regardless they are pretty cool looking so I might consider them. Can't wait to see better pics of predator..
