Gouache is thinned with water to the consistency of condensed milk, then applied with a natural hair (sable...) brush to illustration board. Building up layers isn't a good technique with gouache because any wet paint will interact with existing layers of already dried paint.
Gouache is like water color, it can be thinned with watercolor to a fluid consistency, but it is relative opacity gives it a more rugged quality,ideal for bold,energetic paintings. when wet gouache can be scrubbed,scratched and stumble, and interesting things can happen as color run together and from intricate marble and curdled patterns.
using gouache:
Gouache is equally suitable for more delicate, lyrical style of painting, in which washes of thin, semi-transparent color are build up in layers which dry with soft, Matt, velvety appearance.
With gouache colour, tone may be lightened either by adding white or by thinning the paint with water,depending on the effect you wish to achieve. Thinning with water gives gouache a semi-opaque, milky quality,while adding white gives dense,opaque covering
You could, but it would be a waste. Gouache is best on cold-press illustration board.
The ideal surface for gouache is cold-press illustration board. It is stiff and unyielding, as opposed to stretched canvas,* and has a perfect tooth. *You don't want the paint to crack and flake off when dried.
oil paint on canvas or gouache on handmade paper
Gouache can be used on canvas or paper, although I would say most artists use it on paper. Gouache and watercolors and acrylics are very similar; the primary difference between gouache and watercolors are that gouache paints are opaque and most watercolors are tansparent / translucent. This is not entirely accurate, however, because highly-diluted gouache paints are translucent as well.
Latex or emulsion.

Marc Chagall used many materials. He used oil pastels, paints, matte, Bristol board, chargoal, pencils, colouring pencils and many other art equipment.

You certainly can. It absorbs very evenly into the wood. However, you will have to seal it, as the gouache could reactive or fade. I would suggest a spray clear coat.
Paul Gauguin used oil paints on canvas.
Bridget Riley uses acrylics and oil paints, gouache and screenprint.
