I know that there is not way of knowing for certain from the puppy how the parents fair in terms of being a carrier or cleared, but just because I'm curious:

Does anyone know what the probability is of the parents to be clear if the puppy is clear? How does it change if there are more than one puppy tested as being clear?

here is a link to a chart that was done by Rugosa Basenjis, should give you some idea to the questions you posed.

Thanks, I've seen that before, but forgot about it.

After looking at that, it shows that my answer would be:
Clear pups ONLY means that neither parent is affected, and that does not change with multiple clear pups. The only thing that shows any determination of the parents is a test of the parent themselves (or if their grandparents are clear).

correct. The more clear pups (with no affecteds or carriers) you had from the breeding of the same two animals, the more LIKELY it is that the parents are clear…but it certainly would not be a for sure.
