I know that the black sedan is an early 1970s GM B-body, but can someone identify whether it an Olds, Pontiac or Buick?

Same story goes with the bronw-ish mid 1970s GM A-body in the back ground.

Also I don't know what's that green coupe is (my best guess is 1968 Pontiac Catalina, but I'm probably wrong). I'm pretty sure that other 3 beige coupes are all Plymouth Volare/Dodge Aspen.

I wonder what could it possibly be?
