Hi,

These processes belong to Apache web server. Why do you want to kill them?

If you want to stop them then stop apache. Please see:

http://httpd.apache.org/docs/1.3/stopping.html
http://httpd.apache.org/docs/2.2/stopping.html
http://www.defcon1.org/html/Software_Articles/Apache-start-stop/apache-start-stop.html

first see either it is parent process or child process, if it is parent process kill it directly by kill command and keep the level 9. if it is child process then observer the parent process and try to kill parent process if it is not required by kill command

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

Like omarfarid said, those are from your apache web server.  If your machine is suppose to be running a web server, it's ok to leave them be... unless they are causing other problems, but then that's another issue.

Note that you have to be running as root to kill it.  Try:
apachectl -k stop

they rerun again probably because there is some kind of cronjob . the cronjob will  the status of the process, if the process is not running, the cronjob will run the process.

Don't kill 'em - it's your web server, they're not zombies.

Any to kill processes, use the kill coammmand, man kill to find out the syntax

You can set the number of threads Apache will launch in the apache config (usually /etc/apache2/httpd.conf).  If you want apache running, but with fewer threads, you can lower the number in the config file (StartThreads, MinSpareThreads, MaxSpareThreads). You can also shut down apache with the init script, usually either `/etc/init.d/apache2 stop` or `/etc/init.d/httpd stop`.
If you do not want apache to start any longer with your server, find the default init level for your server, `less /etc/inittab` (it should be near the top) then edit that runlevels scripts and change S##httpd to s##httpd.  The scripts are case sensitive, so by simply changing the S to lowercase the system will no longer start the process.  So for example, you could, `mv S80httpd s80httpd` and apache would not start next boot.
the init scripts should be in /etc/rc#.d where # is your default runlevel, so for me it is /etc/rc3.d
Cheers.
