An astable is a continuous oscillation.
A monostable makes a single output pulse of a calculated duration when it is triggered by an external low-going input.

It has two possible states (high / low). It is another name of the "Flip flop" circuit

More precisly bistable means either state is stable and a pulse changes it's state. flip flops come in so many different varieties as to be a completly different topic.
