This is the sentence:
"... Has established a committee who has/have been appointed as the custodians of ..."
Do I use has or have? Do I use custodian or custodians?

A committee is a singular object (not the the individuals within it) so your sentence would be better as
.... has established a committee which has been appointed as the custodian of ...
I think you could use that has instead of which has if you prefer.
The committee is one thing. The members of the committee are (presumably) more than one.
