  We solve numerically various types of the gap equations developed in the
relativistic BCS and generalized BCS framework, presented in part I of this
paper. We apply the method for, not only the usual solid metal but also other
physical systems, by using homogeneous fermion gas approximation. We examine
the relativistic effects on the thermal properties and the Meissner effect of
the BCS and generalized BCS superconductivity of various cases.
