The first bike that appears is a chrome Kuwahara (although the hole in the gusset has a swage around it-bike an Ammaco)with black steel hubbed Skyways,the second one (yellow), two hole gusset(bit like a team murray) but with black 3 spoke mags,third one(green) looks a bit mid/new school to me,the fourth one,chrome frame,looks like it has Skyways(black) but with completely yellow tyres. The green one REALLY looks like it has REVCORE bars on it.(shape and decal location/width). i'd put money on that they are Revcore bars on the green bike.
