Yes, you can put chalk pastels over acrylic paint. After acrylic paint is dry, you can use soft pastels over the paint so it won't crack.
You can use oil-based paint pens over acrylic IF the acrylic has not been applied too thickly. You can also use water-based paint pens. HOWEVER, you cannot use acrylic over oil. The difference in how these two mediums dry and cure can make the acrylic-over-oil crack.
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.
Depending upon the type of plastic, acrylic paint can be applied directly to the surface. Some plastics will repel acrylic paint, some are very smooth and the acrylic paint will easily scratch off and some have a slight tooth and provide the best surface for paint adhesion. The plastic must be chemically inert so that it will not react with the paint film over time. If the plastic repels acrylics, the surface can be prepared by sanding and roughing the surface to provide "tooth". Try using a very fine sand paper, such as #500 "wet sanding" black sandpaper to roughen the plastic's surface. After sanding, remove dust and coat with a layer of Matte Medium or Matte Gel Medium (let dry) and then one or two coats of acrylic gesso.

The main difference between using acrylic over oil and using oil over acrylic in painting techniques is the compatibility of the two mediums. Acrylic paint dries quickly and forms a rigid layer, making it suitable for painting over dried oil paint. On the other hand, oil paint takes longer to dry and remains flexible, making it challenging to paint over dried acrylic paint. It is generally recommended to use acrylic over oil for better adhesion and longevity in the artwork.
The best technique for applying acrylic over oil paint for a cohesive and durable finish is to first ensure the oil paint is fully dried, then apply a layer of acrylic gesso as a primer. Next, use thin layers of acrylic paint, allowing each layer to dry completely before adding the next. Finish with a varnish to protect the painting and create a unified surface.
Acrylic paint is an insulator because it does not conduct electricity. When dry, the acrylic paint forms a protective layer that does not allow electricity to pass through.

Yes, it is possible to put acrylic paint over oil paint, but it is not recommended to put oil paint over acrylic paint.
No, it is not recommended to paint acrylic over oil because the acrylic paint may not adhere properly to the oil paint surface.

No, the solvents in lacquer are to hot and volatile. The lacquer will cause bubbling of the acrylic paint.
No, it is not recommended to paint acrylic over oil-based paint as the two types of paint do not adhere well to each other. It is best to use acrylic paint over acrylic paint or oil-based paint over oil-based paint for better results.
No, it is not recommended to apply acrylic paint over oil paint because the acrylic paint may not adhere properly to the oil paint surface.
