Two. 0 and 1. Any system uses as many single digits as the nominal base.

Base 10 uses 10: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.

Base 16 (hexadecimal) uses 16: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e and f.

etc.

How many digits are there?

The number of digits in a number system is equal to the base of the system. The decimal system is base 10 and has ten digits. Binary has two bits, which is short for binary digits. Hexadecimal has sixteen digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E & F), and so on.


How many types of binary number system are there?

To the best of my knowledge (which is not completely inconsiderable), there is only one binary number system. That is the system in which each place is worth twice that of the preceding place, starting at 1. A 1 will count the place, a 0 will not. You may have meant how many number system are there 'like' the binary system, that is to say, how many number system are there which, like the binary system, do not use 10 digits. The answer to that is an infinite number. Binary is only special in that it uses the least possible number of digits. Our normal system (decimal) uses 10 digits (0-9). A number system can be made which uses any number of digits. The only three that I know of which are commonly used are the following. Decimal is our normal day to day number system with the digits 0-9. Binary is the number system used by computers and has only two digits, 0 and 1. Hexadecimal is a number system used by programs and has 16 digits, 0-f (that is, it uses 0-9 like normal, but continues by replacing "10" with "a", "11" with "b" and so on, up to "15" with "f"). To look into this more fully, they're called bases. Binary is base 2, decimal is base 10, and hexadecimal is base 16.
