> At the end of the credits we know what became of Starscream. But what about Berricade the Mustang?

It's assumed that Scorponok and Barricade survived, although the original script had a scene where Barricade was killed. The writers hinted in an interview that Barricade might return in the sequel.

Wikipedia says that Bonecusher might have survived Prime's beating (even though Prime apparently beheaded him) and is now hiding out in the jungles of South America.
