Here is e very good explanation of it.
4-Way

what is 3 position ???

The handle has three positions it can be in, like UP-CENTER-DOWN

and on some what is detent??

A "detent" is a feature that will hold a spool in one position, it is usually used for a float position like on a FEL, so the loader will "float"up and down
