What could have caused 1 brake pad to wear down to metal while my other 3 pads are ~50% used?

It's must likely down to siezed slide pins, if it's a sliding caliper setup (more likely), or a siezed piston if it's a dual piston caliper. If it's the slide pins, it's a fairly easy fix - extract ...

If my brakes are making a metal on metal noise, it is pretty much guaranteed I should replace my rotors along with my brake pads?

Squeaky brakes are often the wear sensor, when the pads get low on material they're designed to squeal so you know they need attention. So, you'll almost certainly need pads. As to whether you need to ...

How can a damaged caliper prevent other calipers from fully pressurizing?

Your final thought is correct. Only 1 calliper was faulty. You said it that the pads on the faulty calliper had even wear, which indicates that the slider mechanism was not seized. The piston on ...

Brake pads sliding (?) between reverse and forward?

It is possible that the rear wheels nuts/bolts haven't been tightened correctly, which is allowing the disc/rotor to rotate slightly relative to the hub until it hits the studs, when you brake.
