I too am on multiple lists, one for a PhD Program and one for a masters program. Unlike you, I have no idea what my chances are on either since the directors claim the lists are unranked. Also unlike you, I have not been accepted anywhere, which has made for a very stressful last few weeks just waiting on pins and needles.
The trick with waitlists is that you likely won't know if you got in off the waitlist until april 15th, which is the deadline for most people to accept offers at their respective programs and decline offers at yours. The catch being that if you already have an acceptance you will likely need to make a decision on or before april 15th, meaning that there is a very tight window for a school that has wailisted you to let you know you're in before you commit somewhere else.
I hope this helps to clarify and doesn't just stress you out more.
