1. Is it normal to have more than 1 PID for the script which is being run using cron command?
What is that script trying to do..? Are you calling any other scripts/applications inside your script? If that is the case, what you are referrung may be the child processes.

3. Can i kill all the pid's related to the script and then will cron automatically start(new PID) the script?
Make entries in the script before the startup to see any existing processes and kill it(its not a fair idea to kill the process if you have a neat option to stop the application process/script)..

Something like below can be used to kill the process.

ps -ef| grep "application" | grep " 1 " | xargs kill -9

NAME
kill - send a signal to a process SYNOPSIS
kill [options] <pid> [...] DESCRIPTION
The default signal for kill is TERM. Use -l or -L to list available signals. Particularly useful signals include HUP, INT, KILL, STOP, CONT, and 0. Alternate signals may be specified in three ways: -9, -SIGKILL or -KILL. Negative PID values may be used to choose whole process groups; see the PGID column in ps command output. A PID of -1 is special; it indicates all processes except the kill process itself and init. OPTIONS
<pid> [...] Send signal to every <pid> listed. -<signal> -s <signal> --signal <signal> Specify the signal to be sent. The signal can be specified by using name or number. The behavior of signals is explained in sig- nal(7) manual page. -l, --list [signal] List signal names. This option has optional argument, which will convert signal number to signal name, or other way round. -L, --table List signal names in a nice table. NOTES Your shell (command line interpreter) may have a built-in kill command. You may need to run the command described here as /bin/kill to solve the conflict. EXAMPLES
kill -9 -1 Kill all processes you can kill. kill -l 11 Translate number 11 into a signal name. kill -L List the available signal choices in a nice table. kill 123 543 2341 3453 Send the default signal, SIGTERM, to all those processes. SEE ALSO
kill(2), killall(1), nice(1), pkill(1), renice(1), signal(7), skill(1) STANDARDS
This command meets appropriate standards. The -L flag is Linux-specific. AUTHOR
Albert Cahalan <albert@users.sf.net> wrote kill in 1999 to replace a bsdutils one that was not standards compliant. The util-linux one might also work correctly. REPORTING BUGS
Please send bug reports to <procps@freelists.org> procps-ng October 2011 KILL(1)
