I am not sure what you mean by "types" of numbers.
There are integers with 1 to 4 digits; there are rational fractions.
Then there are surds: like the 13√24 (the 13th root of 24)
or exponents, like 2341 or logarithms such as log2134.
Some of these will be equal but I guess there will still be well over a hundred.
89,999 different numbers i guess
8
6, as long as they are all different
about... 25 just take 5 numbers times 5 numbers
15
You can make 12 different numbers.

98
With 4 different numbers, 24.
8
6, as long as they are all different
you can make at least 25 sums
Assuming that the six numbers are different, the answer is 15.
1000
There are so many different types because they are all used for different purposes in different situations.
Because people make so much!!
