Too many processes?

I got a slight problem here, i have everything up and running on my server and running a backup on it, its expected to take a while so im not to concerned about it, i logged in to virtualmin and found i have about 85 processes running, some of which include kjournald x5, /usr/sbin/spamd with 2 "spamd child" processes, 3x "pop3-login", 3x "imap-login", "/usr/sbin/apache2 -k start -DSSL" with 7 sub-processes identical to itself, and 3x dhclient, in that group there are 25 processes that i have listed, what i am wondering is why are there so many "identicle" processes and what can i do to decrease them other then killing them?
