Yes, you can generally paint high gloss latex over flat latex paint. But you must do all the preparation work in the best tradition of any professional painter. All "flaking" must be removed and the raw wood primed. This will present a "smooth" surface for the new coating. Additionally, everything that is to be painted my be scrupulously clean and free of anything that will restrict the new latex from sticking to the old.
Flat latex paint can be painted over with a semi gloss latex paint. The cover up of the flat by the gloss may require a few coats.
Not without a primer or washing the wall with TSP, the flat will not stick to the gloss
Yes, as long as the surface is clean, oil-free and dulled prior to painting.
Yes, preferably if it is also a latex base.
NO, it won't stick for long.
Yes
You will have no problem painting satin over top of flat paint. Just remember to use the appropriate paint that will stick to the old coating. If the old coating is latex (water based) you can go over it with latex or alkyd (oil based) paint. If the old coating is oil based you can only go over it with oil based paint or a hi performance latex that is specialy made to go over oil. Most latex will not stick to oil based paint.
If you have the satin, you can add flat paint and take some of the sheen off. This would have to be done before application. It will never be a true flat though.
All mouldings were once painted in a high gloss paint because the higher the gloss the more durable the paint. These days most interior mouldings can be painted in either a semi-gloss or satin depending on your personal aesthetics.
Base paint is also known as flat paint, or flat wall paint, or matt paint and is a latex paint. Flat paint is just that, flat or dull with no sheen at all. Semi-gloss is an enamel that dries very hard and can be found in a low sheen (satin) a medium sheen (semi-gloss) and a high sheen (high gloss) Flat paint is usually used on walls and ceilings where as semi-gloss is used in kitchens, bathrooms, doors an jambs because it helps hold back the inherent moisture in those areas.
Add a little talcum powder to the paint.
Yes or it can be the same as the wall paint if it should be flat.
Put a good primer on it.
If you want to turn your satin paint into flat wall paint simply mix one to one. One gallon of flat to each gallon of satin. The flat wall paint will obliterate any sheen the satin once had.

Yes, it will.
No, you can dull satin or semi-gloss but not the reverse.
The flat latex paint will stick to satin or semi-gloss latex paint without any problems. The main consern is making sure the surface is clean and sound before begining to paint, plus use top quality paints for the best results.
Yes, depending on the mix ratio, you will end up with an eggshell or satin finish.
