The 5th - It's the UAZ-469 and the one next to it, it's the GAZ-69 Russian off-road military light utility vehicles.
The 6th - V100 Cadillac Gage Commando US ACP.
The 7th and 8th - top part of the Sd. Kfz. 221 body

The 11th (the 4th in the second row ) - the British post-war FV4101 Charioteer tank destroyer, an upgraded version of the well-known Cromwell WW2 tank. Just parked next to its predesessor in the pic.
The 12th - the front armour plate of the early M4A4 Sherman.
