With extendedglob, the following should work:

  grep -i 'host' **/(*.cfm~(ctpigeonbot|env).cfm)~*((#s)|/)junk*/*(.)

This excludes any pattern which {either starts with junk or contains /junk}
and {contains a / somewhere after the junk}.  Clearly that would only apply
if somewhere in the path there was a subdirectory starting "junk".

I tacked the next bit on at the end just to show the difference, but it's
possibly easier to combine the ~ expressions at the end.  However,
you would need to do the *((#s)|/)(ctpigeonbot|env).cfm trick to make sure
that the name only matched a full directory entry, either in the current
directory or a subdirectory.

You probably don't need the (.) on the end; it just wanted to be there.

Actually, most of my directories contain junk, so I won't be doing that...
