You mean beyond the different purposes, protocols used, encryption, invocation, output, return codes, and their description in the man pages?

try them out and see what happens! the man pages give examples of what they are but it depends on the OS too, on ubuntu (ie linux) man of rsh and ssh is the page for ssh and the same is true of rcp and scp -

rsh/ssh - remote/secure shell (ie login)
rcp/scp - remote/secure copy
telnet - remote connect, good to see if a port is open
ftp - file transfer
