If you are inquiring about reselling the templates that come with a hosting package for which you are the reseller, separately from the hosting package itself, I'd guess that, in most cases, you would not have the right to do it!
I also suspect that the answer to your question depends on the exact details of the deal you're considering, so don't be surprised if nobody is able (or willing) to answer such a "broad" question.
In general, if the seller explicitly states that you can resell the templates, it certainly would make sense if it were, indeed, legal to resell them...
However, that would assume, IMO, that the seller is legally entitled to sell these "master resell rights" --so you would have to know the full, exact details before you could answer the question!
