I'm not sure I understand the question, sorry.

In general, Emacs will use the first font defined for the character
that supports it.  If all the fonts were defined the same, the order
of their look up is not under your control.  So you will be better off
defining specific regions of characters for specific fonts.  Leave the
catch-all definitions for Emacs.
