This is most likely a clone of the main Koha git repo. See

C4 contains the perl modules (libs) unique to Koha. This instance of
C4 is the one being used by your live Koha. It results from selecting
a 'standard' install when running Makefile.PL.

C4 is the name given to a very powerful plastic explosive. Also, see above.

HEAD in a general context references the current bleeding edge of Koha
code in the main repo (master, as you guessed).
It is *not* considered stable and it is *not* recommended for use in
production unless you really understand the potential issues.
The current stable Koha is the 3.0.x branch.

Yup, you can search the lists as well: http://old.nabble.com/Koha-f14380.html
And checkout the formal documentation as well:
Welcome aboard, and feel free to ask all the questions you like.
