The C/L Bipe is a Sterling Flying Fool (kit S12). It would undoubtedly not be airworthy without major structural rehab as Sterling's plywood was poor even when new and would be delaminating very badly by now.

The C/L combat plane in poor condition with the diamond airfoil is clearly a Riley Wooten design called the Demon. It would probably be easier to build a new one from plans or use this one for patterns and measurements to build from than rehab it.

In other pics there's some C/L fuel tanks that appear to be Veco's and Perfects. I see a box claiming to be a 3-line J-Roberts bellcrank. These are still available and sell for around $25.

The framed up C/L stunt plane wing looks vaguely Nobler'ish but the tail and cowl are wrong...
