Dunno, can you make this a separate question?

When you set “force=yes” (default value) context uses the fallback font even
when the character exists the main font.

The name of the font files has nothing to do with way how \definefontfamily
collects the individual files for each style, to do this it uses internal names
and values from the font.
In a case where \definefontfamily can’t find all styles you can select them
with the name of the files:
\definefontfamily[<typeface>][<style>][<family
name>][tf=file:uprightfont,it=file:italicfont,…]

When you use a opentype math font the upright, italic, bold etc. characters
are all in the same file which uses only the regular style (a few math fonts
provide also a bold style which can be useful in headings).
Because there is only a upright math font you have to set a fallbacks
also for the upright style even when the font you’re using is italic, e.g.
\definefallbackfamily[xxxface][math][xxx][tf=file:xxxitalic1,preset=math:lowercaseitalic]
