On a MTB it's usually a clamp that goes around the seat post. On a road bike it can also be screwed on to a soldered tab on the frame.
Sure. There are two things that has to match, the number of gears, and the actuation ratio or the rear derailer. If the rear derailer is a Shimano, then it'll take a Shimano shifter no problem. If it is an SRAM derailer, then you have to figure out if it's the Shimano-compatible version or the 1:1 pull SRAM version. If it's long-pull SRAM, you'll need a long-pull SRAM shifter. Once that's sorted out, unhook shifter cable at derailer. Pull grips off bar, loosen pinch screw(usually Allen head) slide twist shifter off. Slide trigger shifter on, tighten pinch bolt. Slide grips back on. Install shifter cable. Adjust shifting. Done!
IT would very much depend on the vintage and quality of the bike. If it's a fairly recent bike I'd just buy the cheapest Shimano derailleur with the correct hanger (either bolt on or integrated) and the odds are good that it will work.
There is a tube on the right rear of the bike. right in front of the swing arm. It is a hex head bolt.
That would be different from bike to bike. Get a vernier caliper and measure it.
its under the right side of the bike by the front of the rear tire. it looks like a flat hex nut bolt.

Start bike and allow it to warm up. There is a large drain bolt beneath the engine crankcase. Remove the drain bolt and the oil will evacuate the crankcases. Reinstall the drain bolt. Remove the oil filter located on the front of the engine cases. Install a new filter. Bike will hold 3 quarts when changed with the filter.
there should be a 10mm bolt that holds a bracket that holds the front seat down. under the pass seat. It is located in the center of the bike.
It is a waste bike you just burn that bike or put it in ocean.
