I would try the Best Cleaner Ever from ScraPerfect. It is effective and safe--for people and the environment. It removes spray paint and other kinds of paint and yet it has no fumes and is safe for skin. (It also removes adhesive and sharpie markers...) You can Google it--there are lots of videos about it also.
Sure, just don't expect the paint to stay on very well. Porcelain is a very hard surface and don't really take paint particularly well.
No, the color in spray paint is not affected by bleach. A proprietory concrete cleaner or fine sand impregnated with solvent will reduce the appearance of the paint.
It beads up and doesn't dry. It you touch it it will wipe off. It may leave a faint stain, but it won't show up strongly. If you put wax on spray paint then it will make it hard to remove the spray paint and it will also make the spray paint look glossier.
It depends on the type of paint. Lacquer thinner will remove most oil based and latex paints from a paint sprayer, however, spray gun cleaner will remove it better.
scrape it with a razor blade...assuming the tile is untextured porcelain

You can scratch it off but that's not the best way.

Yes, you can use urethane paint on porcelain mugs.
You can't. Prime over it with a good primer.
Acrylic paint is water based, so water or soapy water should be used to clean a spray gun.
It depends on the paint. You'll need to use a paint that can be used on ceramics but you may need to etch the surface, either by sanding, or etching with phosphoric acid first to promote adhesion.
If it is vinyl tile and it's latex paint, rubbing alcohol will remove it. If it is a ceramic or porcelain tile, you can carefully scrape it off or if it is also latex paint, the same thing,,,alcohol will remove it.
