Sure, but 5 minutes is a long time.  A better approach would be to
monitor the squid daemon (or daemons, I've never used) via ps in a
while loop until they are all gone.  Something like:

while ps -ef squidd   # Don't know the daemon name
do
    sleep 1
done

This way it should only wait as long as it really takes to shut it
down, and if it happens to take longer than 5 minutes you'll handle
that also.
