Of course
Well, of the three crontab lines above, the second is the interesting one for you:
You may consider it as a boolean expression, meaning that
script2.sh will run if, and only if, script1.sh finished successfully (exit 0).
This will happen at twelve o'clock.

The first line says that script1.sh will run from 4 to 11 and from 13 to 21 every 5 minutes. The last line says that script1.sh will run every 5 minues from 12.
