    }
},

Is there any solution use Multiple CustomScript in ARM template? Kindly help me to solve this.

Currently , it is not possible to run Multiple CustomScript Extensions at the deployment time.

According to your scenario, you can author an entry point script that calls the dependent scripts, then upload the entry point script, dependent scripts and any other dependent binaries to the script location(Azure storage blob or GitHub). More information please refer to this link.
