Those are the non-Trek/Wars/Transformers that were easy to identify. Most of them can easily be transformers from various years even if the source image isn't. There's a couple of other Gundam ones, like the God/Burning Gundam core lander, but I didn't see it on a quick glance, and there's a lot of dupes on there.
