Corrected entry: The Constructicons make up Devastator. When Agent Simmons, Leo, Mudflap & Skids are fighting Devastator. The Constructicons that are Devastator's head [The Cement Mixer Truck and Long Haul The Giant Green Dump Truck, which is the last vehicle to transform right behind Simmons & Leo] are both seen fighting in their robot modes against the N.E.S.T team members at the same time as being a part of Devastator. Unless they can be in two places at the same time, this isn't possible.

Correction: The constructicons fighting the N.E.S.T. team, and the ones making up Devestator are totally different robots. So, yes, this does mean that there are 2 mixmasters, 2 Rampages and 2 Long Hauls. No reason different robots can't choose the same alternate modes.
