Second from left looks like a PENTI 1 - a East German half frame 35mm camera that came in various colours - took Agfa rapid type cassettes (although the original cassettes were plastic).

The one on the right looks like a Balda 35mm folder..this is based on what I can see of the foot on the bed, which is a bit wider than most other cameras of the era...

Second from right could also be a early Contax SLR - the shutter button looks like it is on a angle, and the Wirgins had a straight shutter button.
