Linda,
It's morally wrong to sell those names to some unsuspecting person (victim, actually). Try to get your money back. It is a VERY safe bet that whoever sold you the domain did not own the commonlaw trademark to that celebrity name. If you hand registered the rest, hopefully the registrar you used gives a couple of days to cancel and you are still within that window.
Just like someone already said, just consider it a lesson learned and tuition paid. I know it sucks, I went through the same thing my first day registering domains.
PS I am not a lawyer, all this is just based on what I have read on the legal section on this forum and other forums.
