You can definitely use latex paint over epoxy. In fact, it is recommended to use latex over epoxy by the paint manufacturers, rather than using epoxy over epoxy. The latex adheres better and if you then want to use epoxy next time you paint, you have a nice coat of latex between the layers. If you use epoxy over epoxy, often the paint will just peel off in layers once some time passes (and sometimes right away).
Yes, but it may not stay on very well. Besides, epoxy paints are very hard and wear resistant, while latex paints aren't. If the epoxy paint was needed the first time, repainting with something much less durable might not be such a wise move.
latex or egg shell
No, you either need to really rough up the oil paint with fine sand paper, or put a base coat on before you paint with your Latex paint. If you don't your Latex paint won't adhere.
yes but not the other way around the latex passes moisture
When you say rubber base paint I assume you mean latex paint. Yes, latex paint will adhere to an existing epoxy finish. However, the epoxy must already have cured. Meaning, it was already applied sometime in the past. A pretty good rule of thumb to go by when you're unsure if two finishes are compatible is to apply a coat of primer. Also, when latex paint is applied to a primed surface it will last that much longer, appear more uniform and will usually require only one coat of paint for proper coverage.

Yes you can.

Yes, oil based paint is very versatile and can be painted over many painted surfaces, including those previously coated with latex paint, as long as the surface is dull and clean.
As long as none of the paint is flaking, you can.
Hot water
Yes it can.
Check the instructions or the technical data sheet for the product that you are using. Some water-based epoxies require a primer when refinishing a previously coated surface.
Any paint and decorating store should have little pads (like wet-wipes) that you rub onto the painted surface. Whether or not the paint rubs off will tell you what kind of paint was originally used.
You can use denatured alcohol to check to see if latex paint is on the wall. Rub a rag moistened with denatured alcohol onto the surface. If the paint melts and is removed by the rag, you have latex. If it just cleans the area, then it is probably oil. It could also be epoxy or xylene based, but that is rarely done in a residential application other than flooring.
