yes. Just sand the surface with a 100 grit or 150 grit sandpaper to insure a good bond.
Do NOT DRY SAND if the paint is older than 1978 as it likely has lead in it which is toxic. Spray with water, then wet sand to not create lead dust.Only if the oil based paint is primer or has a flat finish which allows for proper bonding with the water based topcoat. This effect can be achieved on oil based glossy surfaces by carefully sanding, and priming them before applying the water based topcoat.

Yes you can, but the oil based paint will need to be primed first. Use an oil based primer instead of latex primer.
It is generally not recommended. There is really no reason to use oil based paint except oil based primers.
Yes. You'll need to ensure that the surface is clean and gloss free prior to applying your topcoat though.l
yes you can... you can do oil over latex and latex over oil
Yes. Clean and degloss the oil based paint, apply an oil based primer, then apply the water based paint.
No, it will not stick.
Yes, you can
You can but it wont last, you will have a bigger peeling mess.
Water based paint such as latex and acrylic do not adhere well to oil paint. In order to paint over oil paint you must sand the surface and prime it with a good quality oil or alcohol based primer and then top coat with a water based paint. Oil based paints will adhere well to water based paints sp it is unnecessary to prime before top coating, unless you have had to do any repairs to the surface.
In the past oil paints referred to either petroleum based paints or linseed based paints. Today in the USA petroleum based paints are no longer sold and it is difficult to find linseed based paints though they do exist with a small proportion of linseed oil. Alkyd paints are made with synthetic oil and are readily available and have come to be known as "oil" paint.
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.
There are some water based coatings that will adhere to an oil based surface without using a primer; however, an oil or acrylic-based primer, used as a bridge, will allow you to paint latex over an oil-base paint trouble free.
Yes. Clean and degloss the oil based paint, apply an oil based primer, then apply the water based paint.
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.
yes
You can but it wont last, you will have a bigger peeling mess.
No, you can't .
That is not generally recommended.
Yes, you can paint oil paint over sound water based paint easily, just be sure to degloss and clean the surface prior to painting.

Yes, if the original is in good shape, not flaky.
Oil based paint has a very hard surface which makes it difficult for water based paint to stick to properly. It should be primed first. Water based primer is fine. To make certain the water-based primer has good tooth, be sure to lightly sand the oil-based paint and wipe it down with a tack-cloth.
It will protect the paint as long as you use a water based varnish, never use oil based varnish over water based paint. Tip: "water based enamel= water based finish". "oil based enamel= oil based finish".
