  Let $f:\mathbb{C}^2\to\mathbb{C}$ be an inner non-degenerate mixed polynomial
with a nice Newton boundary with $N$ compact 1-faces. In the first part of this
series of papers we showed that $f$ has a weakly isolated singularity and that
its link can be constructed from a sequence of links $L_1, L_2,\ldots,L_N$,
each of which is associated with a compact 1-face of the Newton boundary of
$f$. In this paper, we offer a complete description of the links of
singularities of inner non-degenerate mixed polynomials with nice Newton
boundary. We show that a link arises as the link of such a singularity if and
only if it is the result of the procedure from Part 1 for a sequence of links
$L_1,L_2,\ldots,L_N$ that all satisfy certain symmetry conditions. We prove the
same result for convenient, Newton non-degenerate mixed polynomials with nice
Newton boundary. We also introduce the notion of P-fibered braids with
$O$-multiplicities and coefficients, which allows us to describe the links of
isolated singularities of inner non-degenerate semiholomorphic polynomials (as
opposed to weakly isolated singularities).
