Three of one dragon, and each dragon pung counts.
A triplet or kong of Red, Green or White Dragon. Each one you hold pays separately, so two dragon pungs are two faan.
Two dragon pungs plus a pair of the third is Small Dragons; all three is Great Dragons. In both cases the named hand replaces these, rather than adding to them.
