Elements can belong to subsets. Subsets can be elements of sets that are called "power sets".
Subsets is one type of an sets
If the set is of finite order, that is, it has a finite number of elements, n, then the number of subsets is 2n.
Venn diagrams are a means for displaying relationships between sets.
For example, if you take the set A = {1, 2}, then the following sets are all subsets of it: {}, {1}, {2}, {1, 2}. That is, all the sets that fulfill the condition that all of its elements are also elements of the set "A".
Subsets of Sets was created in 2001-08.

An element doesn't have subsets. Sets can have subsets.

Yes all sets have subsets.Even the null set.

If the set has "n" elements, then you can make 2n different subsets. The number of subsets will always be greater than the size of the set, both for finite and for infinite sets.
Integers, rationals. Also all subsets of these sets eg all even numbers, all integers divided by 3.
Any names that you like. Often they are denoted by CAPITAL letters.
No. The number of subsets of that set is strictly greater than the cardinality of that set, by Cantor's theorem. Moreover, it's consistent with ZFC that there are two sets which have different cardinality, yet have the same number of subsets.
