In a default redhat install crond is being used to cycle the logs. atd is
being used in conjunction with this and i am not sure about anacron. anyhoo,
i would keep these.

default this is running but not set up. cron runs it periodically to check
file integrity. This will detect trojaned files put on by root kits from
various linuc worms or crackers. (maybe, if it's not trojaned itself :-))

Defaults to local only install in red hat
need this if you plan to use pine, mutt or elm. fetchmail will download your
mail to a local sendmail install and will the others will use sendmail to
send your mail.
If you are connecting directly to an external mail server with netscape,
mozilla or kmail you will not need this. (unless you want to run a mail
server)

Use as root:
/sbin/chkconfig --list
the tail end of this will list all processes under control of xinetd. It is
the rough equivelant of inetd + tcpwrappers on other systems.
telnet, ftp,pop3, and finger servers are some of what are under it's control.
You really want to make sure you will not need to use any service under it's
control.

Nothing to do with netscape, you are thinking of SSL
This is the ssh server for establishing a secure command shell on your
system from another system.
You can connect with ssh. securely copy with scp. or use sftp, a secure ftp
like client. much safer than telnetd

this has to do with NFS file sharing, you are not likely to be using this.
