How do I install more than one InstaVR-generated iOS app?

By default only one InstaVR-generated iOS app on your phone is allowed.

You can purchase the ability to simultaneously have multiple InHouse InstaVR-generated iOS apps on your iPhone.

To achieve this, you will have to purchase the iOS Add-on for Co-existent Multiple Inhouse iOS Apps and once done you will be able to install multiple apps simultaneously.
