Have we have 2 test - install (test sities) - one for IPS 4.7.19 (main site and one test site) and one test site for IPS 5 Beta 5 - with one Licens key?

Your license key allows for 1 live site, and 1 test site which must not be used for production. The only exception to this is if you run a test instance on localhost. You can run more than one test instance on the localhost URL.
