Plastic insulates the prongs from one another, yet is hard enough to keep them at the proper distance to be put into the wall outlet and allow a person to grip the plug.
why are metal prongs of a plug sealed in plastic and rubber
to stop them from moving
The ground prong (usually of a male plug) is a metal tab or rod connected to the conductor which is to be grounded.
A fork has prongs at the end of it. (Actually a fork has tines. A plug has prongs.)
A wall socket (either switched or unswitched) is the place into which the prongs of a plug is plugged in.

Pull the plug first. Now if glue is on a plastic part, rub it with a rag and Goof Off, it will soon soften and be peelable. If on a metal part,like one of the prongs, just scrape it off with a craft knife.

A plug with three prongs.
You will only be shocked if you touch the prongs while they are still in the socket or if there is a defect in the cord or plug. If you be sure to touch only the plastic part you should be fine.

The metal end should point to the #1 plug location on the distributor.

Yes, because the part of the plug that goes into the power point is metal, and the bit around it is plastic.
It is the minimum required to complete a circuit. You need a live and neutral. A two pronged plug does not have a saftey Earth connection. The device operated must be double insulated and have no metal parts visible, that could become live.
If it is a plastic radiator and it is stripped, no, if it is metal yes.
