Yes indeed they can.
A high fired clay pot is waterproof and a glazed pot is waterproof and both are safe for this purpose.
You can generally use a clay (mud) pot in the microwave- you should check the bottom to see if it has "microwave safe" written on it.
NO!
That is a really good question. The answer to that is you can't really microwave it, but if you have a clay baker, it takes about 1 week to bake in a clay baker...

A pinch pot is a small clay pot, made by starting with a ball of clay and pressing a hole on it, then pinching the sides until it becomes a pot.

The cone rating of a clay or glaze is the temperature at which the clay matures. So if a cone 10 clay is fired to cone 5, the resulting pot will not be completely matured. This may or may not cause a problem, depending on what the piece is used for. For example, a cone 10 porcelain which is fired to cone 5 and not glazed will still be somewhat porous.
