Yes, absolutely! For a skill that adds multiple states, the Notetag syntax would be:
<Show State X> <Show State Y>
where X and Y can be different values. You can do this for as many states as you would like for a given Skill, just make sure that the Plugin Parameters for the Window Coordinates are set in such a way that these popups fit onto the screen and that you change the Max # of State Windows parameter to a higher value.
