Not in any standard Fortran, it can't appear in names.  Some compilers
may allow it, but it isn't standard (which is why some systems use it
in system intrinsic names - that way they can't conflict with any legal
user-defined names).

In standard Fortran, the $ may appear in character contexts (i.e. strings)
and in comments.  It can also be used for the continuation character in
fixed form source (and was fairly popular as such, partly because it was
the character least likely to be mistaken for an actual part of the
statement.)

I don't recognize the sample code above as looking like any familliar
form, so I'd guess it probably is just using the $ as part of the
names - but this is not legal Fortran.
