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
No, I wouldn't advise it. Oil based paint and acrylics don't really attach to each other(chemically). In art painting it is done, (waterbased acrylic gesso, oil paint over it) but I was told by a museal expert that these paintings won't last longer than 30 to 50 years.
In house paint, I did use it (on expert's advice) the other way around (oil based primer, waterbased acrylic over it). Oil based primer is stronger than acrylic based primer, and the primer can absorb the acrylics to some extent. the acrylic is the 'weaker' paint and it will allow itself to be carried. But the other way around I really wouldn't try.
No. water based primer will expand and contract at a different rate than the dried and cured oil based paint. In addition the oil based paint will not properly bond with the water based primer. This will eventually lead to cracking and peeling.
Yes, you can put oil over a water based primer.
Only if the 'flat paint' is water based too.
You can paint water base paint over an oil based primer after allowing sufficient drying time. Check the instructions on the label because drying times can range anywhere from an hour to 24 hours.
You can always paint latex ( water based )over an oil based paint as the latex just dries on the surface. However don't paint an oil based over a latex paint. Oil based paints need to absorb into the wood or other surfaces or it will just dry and flake off.

yes. However, you cannot use an oil base paint over a latex primer. If you change your mind on the paint, you must strip the paint before you use an oil based paint on the primer.
Water and oil do not mix. You will need an excellent quality primer specifically designed for this purpose. Answer: A good rule of thumb is never say no to a primer, but once the latex paint has dried, all the water is evaporated out of it. As long as the surface is clean, you can go over latex paint with oil without using a primer. If you do want to use a primer, use an oil based primer prior to topcoat.
Yes, you can,
can i use water base paint over oil base paint
Yes. Clean and degloss the oil based paint, apply an oil based primer, then apply the water based paint.
Only if the 'flat paint' is water based too.
Not a good idea, better to use oil based primer.
depending on the surface finish of the primer. Noirmally its matt in its appearance and will take a water based gloss. However, a primer should have an undercoat applied first unless its a primer/undercoat.
Yes, you can

It's generally much better to use water base primer on drywall.

Yes, if the primer is oil-based too (alkyd is good too)
