  A Smarandache multi-space is a union of $n$ different spaces equipped with
some different structures for an integer $n\geq 2$, which can be both used for
discrete or connected spaces, particularly for geometries and spacetimes in
theoretical physics. This is second part on multi-spaces. Many conceptions in
graphs are generalized by Smarandache's notion, such as multi-voltage graphs,
Cayley graphs of a finite multi-group,multi-embedding of a graph in an
$n$-manifold, graph phase, $...$, etc.. New results are obtained.
