Plumbing pipe threads are squared and conduit pipe threads are tapered.
Yes.
Female pipe thread features an internal tapered or straight thread design that allows it to connect with male pipe threads. The internal threads are typically cut into the inside of a fitting or pipe, creating a snug fit when mated with a male counterpart. The most common types are NPT (National Pipe Tapered) and NPS (National Pipe Straight) threads, distinguished by their taper and shape. Female threads often appear as a smooth opening with visible grooves from the threading inside.

Galvanized Iron pipe
To connect PVC to galvanized pipe, you can use a PVC to threaded adapter. This adapter has a female threaded end that can be screwed onto the male threaded end of the galvanized pipe. Make sure to use Teflon tape on the threads to create a tight seal and prevent leaks.
To connect a galvanized pipe to a SharkBite fitting, you can use a SharkBite transition fitting specifically designed for this purpose. Simply push the fitting onto the galvanized pipe until it clicks into place, ensuring a secure connection without the need for soldering or special tools.
To connect PPR (Polypropylene Random Copolymer) to galvanized pipes, you typically use a threaded adapter or a transition fitting. First, ensure the galvanized pipe is clean and free of rust, then apply Teflon tape to the threads of the galvanized pipe. Next, screw the adapter onto the galvanized pipe and heat-weld the PPR pipe to the other side of the adapter, using a PPR welding tool. This method ensures a secure and leak-free connection between the two different materials.
Yes, this shouldn't be any problem to do.
You can't. There is no fitting to do this. Galvanized has to be threaded.
Male or female sharkbite adapter on threaded end of galvanized pipe or fitting. No other way.
Yes
If you do connect copper pipe to galvanized pipe, you will need a dielectric coupling or else the galvanized pipe will corrode. Same with connecting galvanized pipe to brass fittings. Brass is an alloy that contains copper and therefore the same electrolytic properties will exist unless a dielectric coupling is used. Hope that helps you out.
I find a wire brush is usually enough to clean threads.
A pipe fitting that has both external and internal threads is called a "coupling." Couplings are used to connect two lengths of pipe, with one end having female threads (internal) to receive a male threaded pipe and the other end having male threads (external) to connect to another fitting or pipe. This design allows for versatile connections in plumbing and piping systems.
GI Pipe is "Galvanized Iron" Pipe. These days the pipe will likely be made from steel rather than iron.
