Does it fit every 2012-2015 Outback?

It is listed for the 2.5L H4 engine only, across Base, Premium and Limited trims. It does not fit the 3.6L six-cylinder Outback.

Is this a new or remanufactured alternator?

The listing does not say. Ask the seller before ordering, since remanufactured units can carry different warranty terms.

No amperage figure is given. It is described as a stock replacement, so expect output in line with the factory alternator rather than more.

One alternator. No pulley, belt or mounting hardware is listed, so reuse your existing parts unless the seller confirms otherwise.

It is worth inspecting the serpentine belt and tensioner while the alternator is off, since a worn belt can mimic a charging fault.
