No, there is no limit to the amount of questions per category or subcategory.
A subcategory; category
The category called "Cleaning" is a subcategory of Home and Garden, whereas the subcategory of "Cleansing" is a subcategory of Alternative Medicine. The former category deals with questions about cleaning in your home; the latter pertains to the state of health of your body.
Usually if you add a question to the subcategory of a main category, it automatically removes itself from the main category. You don't *have* to remove questions from main categories if you add them to a subcategory, but doing so would make the site a little more organised and less cluttered.
