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.
Do you realize that you can get FLAT ACRYLIC PAINT. Flat paint refers to the gloss level. You may want Gloss, Satin, Lowsheen or Flat. Acrylic paint on the other hand refers to what the paint is based on or what binder is being used. Acrylic paint is also refered to as waterbased paint. You most likely are referring to putting flat acrylic over lowsheen or gloss acrylic. In answer to your question - as long as they are both acrylic than you will not have any problems. I am in this answer assuming that you are referring you house paints. If not than the same principle applies - acrylic over acrylic is fine. To keep acrylic from going glossy just don't polish it.
The basic difference between the two paints is that latex paint is water-based and acrylic paint has a chemical composition that gives it elasticity. (But, there are "acrylic latex" paints, with varying degrees and properties of both.) Outside house paints are moving away from latex to 100 percent acrylic because the latter easily expands and contracts with heat and cold. As a result it holds better than latex. And there is a difference in price. Latex paint is much less expensive, but remember that if you use latex over the more expensive acrylic, the surface will have to be painted again much sooner.
Once it dries
The House has cloture.
No you can not. If you do your painting will go soggy

Acrylic paint is a fast drying paint containing pigment. It is safe to dilute it with water, but will become water resistant after drying. A common interior house paint may contain both acrylic and latex paint, because acrylic paint is typically more expensive.
I recommend that you DO Not use exterior paint on interior surfaces of your home.Exterior paint is designed to cure outdoors. It contains chemicals to discourage mildew growth. These chemicals should be considered dangerous to the health of human beings and their pets.
by getting a life
You usually go and stay at a friend's house while the paint dries, so you don't breathe in the paint fumes.
Oil based metal priming paint along with a 100% acrylic latex exterior house paint.
If I understand you correctly, you want to know if you can cover a latex paint covering with an oil based covering? the answer is yes. need to prime? only if you think the walls need priming. Rule is: oil over latex, not latex over oil without proper prep- alkyld primer or similar
