As you saw in man signal, there are dozens of ways to control processes. Here are the commonly-used ones:

kill -STOP [pid]
SIGSTOP (17,19,23) stops a process without killing it

kill -CONT [pid]
SIGCONT (19,18,25)restarts a stopped process

kill -KILL [pid]
SIGKILL (9) forces the process to terminate immediately and performs no cleanup

kill -9 -1
Kill all processes that you own

SIGKILL and SIGSTOP can not be caught, blocked or ignored, but the others can. These are your big guns of last resort.
