Not without removing the head, the pistons can't be lowered past the crankshaft. If you remove the head you can remove the rod bolts at the bottom and push the piston through the top.
The support pistons need to be replaced.

If you are talking about the crankshaft rod bearings, you can just remove the oil pan, and replace each crank bearing one at a time without actually removing the pistons. But to replace the piston pin rod bearings the pistons will have to be removed. IMO, if any of these bearings are worn bad enough to need replacing, then the engine needs a complete overhaul.

Rebuilt. Usually the pistons are replaced etc to work like new.
No. Crank and main bearings can be get at by dropping the oil pan, but to get to the small end rod bearings you've got to get the pistons out.
8 dollars each to press new rods on pistons.
Caliper pistons should retract if calipers are in working order. Calipers need to be removed and rebuilt or replaced. A brake fluid flush is highly recommended.
Absolutely. The ONLY parts that aren't interchangeable between a 2 bolt and 4 bolt block are the main bearing caps themselves. The crank, rods, pistons, camshaft, oil pump, etc, are ALL interchangeable. So yes, the pistons will work just fine.
Quite simply you have to remove the pistons. first drop the oil pan second disconnect connecting rod end caps third either remove crankshaft or remove cylinder heads then finally remove pistons. removing pistons are commonly removed from the bottom of the engine. they are pushed out of the top where the cylinder heads sit. Once removed you can replace the rings and then you have to get a piston ring compressor to reinstall the pistons.
no! you need to push the pistons back into the calliper! you may need to turn them.
