Not a standard, default setup; you've installed and enabled other
services which aren't turned on by default.

Yes, those services can be turned off in most environments; still,
you should verify that there aren't any users for them before
removing them entirely.

H.323 is usually used by Voice Over IP applications. To find out
what particular application on your server is listening on that
port, try the following:
# lsof -Pni :1720

This depends very much on the particular application; it may be
started in rc.d or via inetd.conf.
Most of these questions are asked rather frequently; their answers
can be found in the archives and on google.
