I have to agree, the planes are, in order of picture:
1) foam Apprentice
2) F4U Corsair with decals located wrong. That "star and bars" should be on the bottom of the right wing, not on top of the nose
3) P-40 Warhawk with decals wrong again. The US Army was actually supposed to be on the BOTTOM of the wings, not on top. It's also missing the star on top of the right wing as it wasn't until late 1942-early 1943 that US planes dropped the top right and bottom left insignia and added the bars on each side, like on the Corsair
