Here's the ones you get to see or hear in the video game. (from order)
Whiplash (in the comics he is known as Blacklash)
Madame Masque a.k.a. Whitney Frost
Titanium Man
Controller
The Melter
Obadiah Stane a.k.a. Iron Monger
Only 5 of them you get to fight though personally (Whiplash, Titanium Man, Controller, Melter, and Iron Monger). Well, considering one of them you don't actually see while fighting him (Controller). And there is only one villain that you only talk to, rather then fighting her (Whitney Frost). The villain that was chose for the movie is Iron Monger.
