  In Part 1 of this series of papers, we described a general method for
determining the flavor symmetry of any 5d SCFT which can be constructed by
integrating out BPS particles from some 6d SCFT compactified on a circle. In
this part, we apply the method to explicitly determine the flavor symmetry of
those 5d SCFTs which reduce, upon a mass deformation, to some 5d N=1 gauge
theory carrying a simple gauge algebra. In these cases, the flavor symmetry of
the 5d gauge theory is often enhanced at the conformal point. We use our method
to determine this enhancement.
