Well, as those are from different packages using different idioms,
several regexps would be the easiest. In Pd itself everything is done
the same way.

replace 'class_sethelpsymbol(*_class, gensym("' with for example
'class_sethelpsymbol(*_class, gensym("help-' to add "help-" It's not
really hard.

Uses the default, so nothing to do.

This is tricky at a first look. But basically it also just is: 
s/(class_sethelpsymbol.*?)help-\*\.pd/$1\*\.pd/ 
or similar. 

To append "-help" to the end of the file use: 

$ perl -pi.bak -e 's/(class_sethelpsymbol.*?)help-\*\.pd/$1\*-help\.pd/' maxlib/*.c


This is a bit naive in that it assumes that the help-symbol definition
is on one line. It's too late here to think about how to do multiline
regexps. You probably just have to search for a closing brace.

See maxlib.

See maxlib.

I think, external packages should be fixed by the maintainers. If
there is a consensus, things should be rather easy to adapt.
