bisque is the name of the hardened clay called after the first firing in the kiln.
Clay is fired in a kiln.
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.
You'd have a salt reaction with the clay body and depending on firing temp achieve a salt fired piece...
Bisque is the general term for any unglazed clay that has been fired. In high fire pottery a piece is generally fired without glaze at a lower temperature and then glazed and fired at a higher temperature.

When clay has been fired and is a creamy white color, it is called bisque ware. Bisque ware is pottery that has been fired once and is ready to be glazed and fired again to achieve its final color and finish.

It can be. The grain is called grog, and it helps make the fired clay stronger and more resistant heat stress.

Of course not!
Clay can contain air bubbles which contain water. When the clay is fired, the heat rapidly expands that water vapor, causing the piece to explode. Therefore, clay pieces should be hollow, with a hole for expanding air and water to escape.
If clay is a rock
Porcelain is a very fine and delicate clay body and as such is more likely to chip than stoneware which contains grog, a pre fired clay, that strengthens the piece.
