Yes! The muriatic acid will remove epoxy paint on a concrete floor. Usually the epoxy paint will bubble up and will require a flat-blade or wire brush to full remove and.... repeat as necessary. be sure to nuetralize the floor when finished with (1pound of baking soda to 5 gallons of water). I got this reference from http://foundationarmor.com and it worked!
It depends on whether it is a water (latex) based paint or a oil based paint. If it is oil based paint it may not come out, but if it is a water (latex) based paint use 'Goof Off' or other latex paint removers with a wire brush. I have used 'Muriatic acid' on some concrete appications.
Best to remove the epoxy first, otherwise you could experience some peeling issues. If you insist on not removing the epoxy, be sure to remove any grease or oil, clean and sand the surface flat so the floor paint has a solid surface to gain a tenacious bond.
How are you going to wash the concrete to get rid of all of the acid? If you don't get rid of all the acid, paint is not going to stick.
No. Latex paint is not affected by muriatic acid.
It is best if you do remove the old paint first.
Muriatic acid will do it,but take extreme care - it can be very dangerous to use
It will remove pigeon feces
You must remove the old epoxy coating before pouring the new floor, for otherwise there will be no bonding. If the epoxy coating is thin (e.g, paint) then it may be possible to remove it by hand sanding. If it is a thick coating, then sandblasting is probably the best method. In either case, appropriate dustmasks and other safety precautions are essential. Good luck
There are concrete paints available. A three step epoxy paint give a very attractive finish. Both products are available at Lowe's or Home Depot

either epoxy or chlorinated rubber

A good degreaser should work. Also, look into muriatic acid, that is supposed to be a good concrete cleaner.

I wouldn't. I would try to get the first one to cure somehow, possibly by warming that area.
