The red wing one looks like a bi or triplane because of the interplane strut fittings on the wing, but it's not a DR-1 because they have a full-flying rudder and this one has a little bit of vertical stabilizer. The elevators definitely have that Fokker look though.
The silver-winged plane also has fittings for interplane struts and with the way the wing is swept I would think it's another sport-scale biplane of some sort.
Neither is ringing any bells for me as far as full-scale aircraft are concerned, so they may be RC only designs.
