A *checkbox* is there to show a *checked* or *unchecked* state.

If you need 4 different states, then it is not a checkbox but just some
element which shows 4 states. And in most cases a radio group is much
better for this - then users can clearly see what options are available
and can choose one of the options.

No. You need to implement it on your own or check if Angular, React, Vue
or Bootstrap have a component for that.
