In your example you do not need these. The ifxetex package offers to \ifxetex …
\else … \fi, is unknown to me, it looks like a command to be used in a class
file.

The fontspec package loads the other two.

For the block above you can use
\defaultfontfeatures{Ligatures=TeX} %formerly [Mapping=tex-text]

How do these texts appear in an Unicode aware text editor? Could be the fonts
are not perfect.
Can the shape be improved by loading the polyglossia package and using, in the
preamble, these?
\setdefaultlanguage{sanskrit} % maybe devanagari works too, but I
don't see this documented
\setotherlanguage{english}
For this you would need to make four different test cases and could only test
one font by the LaTeX document, the one used by
\newfontface\sanskritfont[Script=Devanagari]{<font>}
\newfontface\englishfont{<font>}
or
\newfontfamily\sanskritfont[Script=Devanagari]{<font>}
\newfontfamily\englishfont{<font>}
Can you improve the shape of the characters by using font features in their raw
form? for example:
\newfontfamily\sanskritfont[Script=Devanagari, RawFeature=+<this>,
RawFeature=+<that>]{<font>}
You can also switch off certain font features by using "-" instead of "+". Note
that XeTeX is not perfect yet in shaping Indian scripts.
