An old 2 hole receptacle can be changed to a 3 hole receptacle that will accept a 3 prong plug, provided a ground wire is available at the box and connected to the ground (green) lug on the new receptacle. A 2 hole receptacle has a hot and neutral wire, while a 3 hole receptacle will require a ground wire connection -- in addition to the hot and neutral wires.
Black wire is HOT, white wire is NEUTRAL and bare or green wire is GROUND. The black wire goes to brass colored screw, the white wire goes to silver colored screw and the bare wire goes to green screw that is connected to the metal "frame" of the receptacle.
The NEMA 6-20R is a 2 pole 3 wire grounding receptacle that is rated for 250 volts. It is not meant to have a neutral wire connected to it. The receptacle is designed to have 240 volts connected to it.

If the plug is melting it is because of a heat build up caused by loose connections. If the plug is not a moulded plug check that the screws are tight. If it is not that, then the plug blades are not tight enough in the receptacle. Change out the receptacle on the generator. Draw a picture of the receptacle and mark where each wire goes. The best way of doing is is when you have the new receptacle take one wire off of the old receptacle and put it in the same position on the new receptacle. Having tight blade connections will prevent the plug overheating and melting.
The types of wire you can use on duplex receptacle with pressure terminal are labeled on the receptacle, next to the holes. AWG 14 and AWG 12 are the typical wire gauges used in this application.
In countries that use a single phase split secondary service you can. In modern homes this is the type of circuitry that is used for kitchen split receptacles. On the receptacle the tie bar is removed from the "hot" side of the receptacle. A red wire of the three wire cable is placed on the upper terminal of the receptacle. A black wire of the three wire cable is placed on the lower terminal of the receptacle. The white wire is placed on the opposite side of the receptacle under the silver coloured screw. This will give you a full 15 amps capacity on the top portion of the receptacle and a full 15 amp capacity on the bottom half of the receptacle.

Green typically represents a ground so you would connect to the bare wire at receptacle or look for a green headed screw.

You will need a receptacle that you can wire each outlet separately (not jumpered). You would then wire the switch in series on the line conductor with the outlet you want switchable. Wire the other outlet directly to the power source. You can jumper the neutral from one outlet to the other.

Use the 4 wire if possible. You would only use a 3 wire for an old appliance.You shouldn't if possible. The 3 wire has no neutral wire as the 4 wire does. Som applications require the use of a 3 wire and some don't.

Yes, this is a safe connection. A range is usually wire rated at 40 amps and the manufactures do not make a 40 amp rated receptacle. The code requires the next highest rated receptacle be used which is a 50 amp rating. This is why the range receptacle is rated at 50 amps. This receptacle is known as a 3 pole 4 wire grounding receptacle, 14-50R 125/250 volt. Black wire to terminal X, red wire to terminal Y, white wire to terminal W and ground wire to terminal G.
