I find your meaning a bit difficult to understand. -You don't paint and prime together. -The primer must be applied first and become totally dry before painting is carried out. If you're concerned about covering ability, use a good thick primer like Kilz. It will completely hide anything.
If the masonite is pre-primed, then a paint and primer in one will work fine. If it is bare, then you need to treat it like wood and either give it two coats of the paint and primer in one, or better, give it a coat of primer, then paint.
First apply a good, even coat of primer (kilz interior primer/sealer works well on paneling) Once the primer has dried completely you will be able to see clearly where any holes or cracks are in the paneling, as you will want to fill any such voids before you apply the paint. When the primer is dry and all the nail, tack and screw holes are filled you can then apply the paint. I like to use a short nap fleece roller cover for surfaces like paneling. The fleece (sheep skin) rollers are a little more expensive but they do not spatter paint everywhere like other roller covers and they last a lot longer.
Many artists (painters) use oil based paint. Some artists prefer to paint on masonite board rather than canvas. The masonite board often first coated with gesso paint. So oil on masonite would be a painting of oil based paint on masonite board.

It will work over another latex paint, however it won't be as scrubable as a normal top coat, and it won't adhere as well as a paint over a primer. Better to apply the primer, then the paint. If the surface is clean and deglossed though, you really don't need a primer and can coat the surface with a quality wall paint.
Probably the primer surface was contaminated before the topcoat was put on. Another option is that the paint was applied in hot weather, over a surface that was not cool enough to paint over. Still another option is that it was applied with a foam roller using too much pressure. That could have introduced air into the surface. The fix is to sand the surface smooth, clean, then reapply the paint according to the manufacturer's instructions.

Masonite can be painted, but it needs to be sealed first. Sand the siding with 80-grit sandpaper or a sanding block, but do not scrape the siding, as it can dislodge chunks of the siding. Apply a layer of primer before painting.

Faced with this, I had to paint it, first a white primer then the paint you want If your panelling is stained rather than painted, I advise that ordinary household bleach will do the trick as well: Be sure to properly ventilate your area, and HAVE A FAN READY!
It's always best (for the best quality) to paint with primer first, then your regular coat of paint. Let the primer dry sufficiently.

No you can not use primer as your paint because it has no sealing properites in it.
Paint primer is essential for many projects. If primer is sprayed onto the surface before painting, it will allow the paint to better adhere and create an even surface.
Yes, you can because brown primer isn't that dark of a color.
No
