Clockwise from top:
Tu-2
J2M 'Jack'
Ju188
Ki-45 'Nick'
Yak-3 (I think)
D-520
You have 4 out of 6 right. The top four are right, but the last two are not. They are small so I can see why you missed them. They are "suppose" to be the Mig 3 and a G55 Centauro, but after looking at the D-520 those two almost look alike any way.
Well done Karnak, even with my feeble attempt at drawing them ya did great. <S>
