My processes, they are

I've been learning a (very) little bit about Unix and AIX while doing some maintenance on our company's ERP server. I've been finding a lot of defunct processes. I have a few very n00b questions.

I've been listing the processes by user (using ps -fu <username>) and also systemwide (using ps -aef) and I see a lot of defunct processes all day long. Sometimes I attempt to kill the processes (usually using kill -5 <pid> <ppid>, but sometimes have to use kill -9 <pid> <ppid>). But killing these defunct processes is like a game of whack-a-mole: as soon as I kill one, another pops up. So I was wondering...
1) Do these defunct processes need to be killed?
2) Are these defunct processes hurting anything, other than a minor drag on our CPU?
3) Is it common to have a lot of defunct processes on a medium-size system with ~30+ users?
4) Does having a lot of defunct processes say anything about the stability of our ERP system?
