Left and right nipple and coupling / union / TP coupling
yes. A no-hub coupling or FERNCO (brand name) coupling work well.

There is a coupling that almost all plumbing stores should have(including lowes). Its name can vary but is commonly called a dresser coupling or a raybolt.
The female coupling connects to the engine (nozzles have female couplings, engine apparatus usually has male connections), so the male coupling always points towards the fire. With that, if you're following a hose, say out of a building, you would want to find the male coupling and follow the hose behind the male coupling.
don't do it, call a professional plumbing/mechanical contractor to fix it properly.
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.

Pure anhydrous lanolin will stick the longest, petroleum jelly is really easy to come by.
In most civilized countries where there is indoor plumbing and codes that protect the citizens from cross connections
