A supervisor can take as many categories under his or her wing according to how capable the supervisor feels about handling them. The sky's the limit.
(See the Related question.)
You can go to browse categories and click on which one you would like to supervise, then click "supervise this category" which will appear on the right side of the page.

There can actually be a multiple number of supervisors in one category, I've once seen 4 supervisors in one category! But it depends on how busy the category is, sometimes and usually the category may need more then just 1 supervisor for one category of interest. So there are usually a multiple number of supervisors, supervising a category. But usually less than 5, but hey, the more the merrier!
The easiest way is to check it daily for changes, new questions, flagged questions etc. Always remember though, that unless your in one of those rarely found (deeply buried categories) there will be more in any one day than you can do.
Tricky one to answer. Supervisors don't supervise a set number of contributors - they supervise individual categories. For example - I supervise the Snakes category. Some categories will be more popular than others - and thus attract more contributors.
This one's a bit difficult to answer.According to answers.wikia there are infinite and theworldofanswers say around 3000 categories.Maybe, a supervisor will give the answer more precisely.Note that new categories are added frequently so there's no stable report.
No Ninjambo is the supervisor for WikiAnswer. Sometimes categories have more than one. They have been inactive since November 2011 if you are interested
Probably one of the categories in the related link - check the sub-categories too - in case there's a specific area you're interested in.
Well, it is mainly up to you, Don't forget, a Category Supervisor looks after certain categories, whereas a floating Supervisor maintains every category, just 'Floating'. Hence the name. So it depends whether you prefer just one category or not.
Category Supervisor - A Category Supervisor oversees one or more categories of interest. Often, those employed (or hobbyists) in a certain field will choose to supervise their category of expertise.Community Assistant - These members help the community, including Supervisors, to be more efficient with the wiki aspects of Q&A (asking and answering questions, editing and so on). A CA performs the less exciting tasks, which in turn makes the time that others spend on WikiAnswers more enjoyable and productive.(See the Related link below for more information.)
A Supervisor is a regular/knowledgeable contributor of a particular category. Age does not matter to become a supervisor. Anybody who is knowledgeable in a topic and is mature and sensible enough to take care/supervise a category can become one. The role of a supervisor is not something that can be asked and obtained. It is given to newer people on the recommendation of existing senior supervisors/mentors etc.
Yes, you can Supervise more than one category.
