Does the rj45 tester test the 8 wires plus the screen? i.e. all 9 conductors in stp cables?

The RJ45 connection does not test the ground. However, if you touch metal components of each RJ45 connector on the cable to the metal rings around the 1/4" testers, then the ground should tone out if it's connected.

Will this test cables with different connectors on each end? for example, a trs to xlr adapter cable with 1/4" trs on one end and xlr on the other?

Yes, you can test cables with two different type connectors at the same time.

Where (in what country) is this made?
