Stop depends. If the combatants can't act during a time stop, then whoever stops time first gets the advantage. If they are aware of their surroundings and can still stop time even while frozen, then yes, the 2nd time stop will cancel out and both fighters will move, like what happened in Dio VS Jotaro.

For slow however, different magnitudes of slowing exist. A person could slow time to half its speed or put it to a near halt. In this case, the person with the weaker time slow will still be slowed, but to a lessoned degree thanks to their own ability.
