Absolutly! You just have to check to see if the primer is first an exterior primer and if it will stick to glossy surfaces. You can lightly sand to rough up the surface or just clean the surface and apply the primer. For oil based primers I would recommend Beauti-tone's fast dry oil primer or Zinsser's oil based cover stain primer.
No. You can use lacquer on oil too. Varnish will work well with oil stain as do any of the wax finishes
Yes, that was the original intention of urethane.
You can paint water base paint over an oil based primer after allowing sufficient drying time. Check the instructions on the label because drying times can range anywhere from an hour to 24 hours.
Lacquer thinner evaporates quicker. It is cleaner or leaves less of a film than paint thinner. Lacquer thinner will thin most solvent based paint but paint thinner shouldn't be used to thin Lacquer. Lacquer dries from the surface painted out and enammal dries from the surface of the paint down to the surface painted. Using the wrong thinner affects how the paint dries and may affect the final finish.
Yes, as long as the polyurethane is oil-based.
Yes. But you can't do the reverse. So if your primer is lacquer-based you can spray an over-coat of enamel on the top.

Remove all dirt, oil, rust, sand lightly, I would recommend a primer first and then apply a at least 2 coats and you will be fine.

You can apply "oil" based polyurethane over "oil" based enamel, you can also apply "water" based polyurethane over "water" based enamel, never mix the two, there's to much of a chance for problems.

Yes, you can use latex paint over poly but you have a few steps to do before you can apply it. First, whether the poly is oil or water based, you'll want to sand it to give it a tooth (something to grab onto). Make sure to wear a mask and goggles. Next, prime the surface you want to paint. You can fill any hole or fix imperfections over the primer but you'll have to prime those areas again if you do. After you're priming is done, you can roll out your paint. Quick note: if the poly is oil-based, I would use an oil based primer (Zinsser"s bin 1-2-3 oderless oil primer, white can with yellow flag on it). You can roll latex over this primer.
depending on the surface finish of the primer. Noirmally its matt in its appearance and will take a water based gloss. However, a primer should have an undercoat applied first unless its a primer/undercoat.
Be careful applying lacquer as a top coat over latex or water based paint. The paint will often "craze" (bubble or sag) when lacquer is applied to it.
Lacquer thinner will thin many types of oil based paint, but not all. -Experiment with a little first.
