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.
No, it won't keep a good adhesion.
You can paint over wall paper. However it is recommended that you prime with an oil based primer. Kilz Original for example. Most wall papers use water based glues for adhesion. If you put a waterbased topcoat over the the wallpaper it could penetrate the wall paper and cause the glue to release. You can use a waterbased top coat such as Kilz Casual Colors over the top of the oil based primer.
Generally speaking, you don't brush lacquer....it has to be sprayed. With that being said there are probably some products that you can brush on if you feel that you must. You would want to use either a china bristle brush, or a "natural" brush. Please know that when you use lacquer thinner to clean your brushes, it may soften the glue that bonds the bristles to the handle. I would use a polyurethane or urethane if you need to apply it by brush. You can put either on top of lacquer if you want to (but you cannot put a lacquer on top of the poly).
Yes, you can put polyurethane paint over eggshell in latex or eggshell in oil.
you can paint over latex paint with latex enamel.
yes you can!
Lacquer can cause the paint to bubble or crack due to the very hot solvent that is a part of lacquer. If you want a clear coat over paint, a better choice is spar varnish over oil base paint and arcylic urethane over latex.
They have approximately the same drying rate. If you wish to speed things up a little, put a fan on in each room you paint to circulate the air.

If the Enamel is an original baked finish there should be no problem. Many DIY touch up paints are made from Acrylic Lacquer. If however the enamel is air-dried then the solvents in the lacquer will react and cause the enamel to bubble and craze. Enamel paints become hard on the surface but stay soft underneath if not baked to harden them. The lacquer is able to penetrate this outer layer and react with the enamel paint.
put a cover over the over paint then you get get the two paint mixed
