The start.sh

Are you expecting the cron to start every 5mins or is that a mistake, also try this commandfor i in $(seq 1 3);do screen top;done
and you will see that only one instance of the screen program is started! So I think the way you running screen might be the issue!

Are you expecting for the newscreen
to run as a background process? or do you expect to open a terminal window?

Either case, the best way to debug a cron job (my opinion) is to output everything to a log file like this*/5 * * * * /bin/sh /home/my/folder/to/start.sh >> /home/my/folder/to/start.sh.log 2>&1
.
