Interesting challenge. But can you provide a greater image or closer shots of the single bodies? Most models are very difficult to guess without seeing them properly. Also the Leica (2nd row, rightmost column): I cannot tell the model.
Next to the Rolleicord is one Exakta lens and Exakta macro bellows. The third object in that group is too black and feature-less to identify, possibly another lens, but might as well be a small pouch for some accessory...
