Is there a pad sensor on both the Left and Right side of the rear brakes? I'm seeing conflicting answers, and some brake kits that only contain 1 sensor, so I figured somebody here would know.,

There is a pad sensor on each pad. The four sensors are wired in a one loop around the car.
Since they are fragile, some pad kits include one sensor in case you break one.
Always have one more sensor just in case you break both is a good idea.

The rear brakes are Audi calipers, they only have the sensor on one of the pads, but there are sensors for both the right and left wheels.
