"rc" is in Debian's "main" section, so I assume it's also Free Software.
As for oash, yes, that makes no sense (how many people use that crap anyway?).
Feel free to remove it.

For ksh, there might be support in there for versions of ksh that still
aren't Free Software, but the I doubt there's much of sh-script.el's ksh
support which can't be used with a Free ksh.

Historical accident.

Agreed.  Although, there is a bit more to it than that: e.g. we rejected
support for C# because the Mono version was so poor that it was clearly
mostly supporting the proprietary version.
I haven't followed Mono's development very closely, but I'd welcome C#
support in Emacs.

I try not to.
