Top-right is Psycho Mantis-tan. His appearances in the trailer are pretty fragmentory, but I got the impression that he was actually helping you.

Bottom-right is Volgin. The FOX unit sneaking suits from Portable Ops have those leg things, but the bare arms are all Volgin. He seems to be a hallucination, and probably won't say anything (his Japanese VA passed away).

Bottom-left, no idea. Best guess: Prototype super soldiers in the same vein as the Perfect Soldier project and eventually the Cyborg Ninja. Incidentally, take another look at the trailer when these guys show up. The first time they appear they're almost completely obscured by dust, but you can just make out some crazy Silent Hill posing. We haven't actually seen anything quite like that elsewhere in the series; the closest resemblance would be to the movements of the Sorrow (Gray Fox had somewhat similar spasms, but those looked like what you'd expect from a normal seizure, while these movements and the Sorrow's look creepy for the sake of creepy).

Top-left is metal as fuck.
