Can this be used to test the efficacy of EMP blocking cages and pouches?

It depends what frequency range you are testing and if you have the proper pickup antenna. The EMP noise source could be inside the cage/pouch and the analyzer with probe on the outside. Or, the analyzer and probe is inside the cage while the EMP noise is outside. Second scenario would be tricky to trigger and capture unless you use the waterfall.

can this be used to display and analyze noise on an AC power line?

You might be better off with an oscilloscope. The TinySA does not have high input impedance and a direct measurement on the power line would likely damage it (and be very unsafe).

Is this suitable for testing tv vhf and uhf signal strength?

Not an expert on TV VHF and UHF, but I believe the TinySA range covers the UHF and VHF spectrum. With some calibration and manual setting (research on YouTube) it will provide accuracy that meets most needs. It is not a $2500 SA, so expect a certain amount of "ok, but its only $50 bucks". Also, ATTENUATE if signal strength/input is expected to be high. Again, research videos with professional testing from engineers. There's plenty of help online.
