My comment on the other thread may have been a little harsh and I apologize. These are some gorgeous examples of Trioceros for sure. I believe the quads, at least the male is a T. quadricornis gracilior.
I see some gracilior traits as well, horns and some of the coloring. but they do not have the tell tail red claws.. Could be quad/grac cross??
