The drive shaft does not leak. It is either the pinion seal or the trans. seal. Either one, the drive shaft has to be removed. The rear seal should be done at a garage, but you could do the front.
It shouldn't

Depends on where the leak is falling from it could be the rear main seal leak, transmission back part connected to the transfer case, or a front main seal leak, the transmission part connected to the engine block also a possiblity is the shifter gear box if you have a standard, which also be in the front near the front main seal.

The rear, or tail shaft, of a transmission has a seal around the output shaft. The drive shaft will have to be removed and the seal replaced.
Replace it.
As soon as possible.
yes there is a seal on the front of compressor that can go bad and leak freon.
It can leak from the front seal, or the cooling lines that run to the radiator. Or it could leak from a cracked case.
On your Ford Explorer , 4x4 , you have a leak at the PASSENGER side front axle seal ( I have had my passenger side front axle seal changed 3 times now on my 1995 Ford Explorer ) The seal doesn't cost very much , the cost is the labor and I would say it takes about 1 and 1/4 hours to do the job
