I think the ones circled in blue are Roland CII based off being 2 seaters, and the shapes of their tails. Plus there are wings that look to have an MG mounted on top of them. I think the green ones are albatross. They're clearly one seaters, have the right looking tail structure and might have the side mounted radiators that were on the DII. I can't really tell from the struts on some of the available wings. The ones in red, I just can't figure out. I'm pretty sure these are H&R like I said above given that there's the Taubes, I've tried comparing them to H&Rs catalog with limited success. Those assholes don't have any product photos on their website.
