They are both sets of positive integers.
The set of counting numbers greater than one.
Three sets
6 if order doesn't matter
They are all sets that contain it. It belongs to {-400}, or {-400, sqrt(2), pi, -3/7}, or {-400, bananas, France, cold} or all whole numbers between -500 and -300, or multiples of 5, or negative composite numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
They are both sets of positive integers.
Not at all. The definition of a composite number is one that has more than two factors - the exact opposite of a prime.
There is no prime composite number; an integer greater than 2 can be either prime or composite, but not both. Nor can you list all the prime number and all the composite numbers: you have infinite sets in both cases.
There are infinitely many sets: Some examples: {346}, or {346, sqrt(2), pi, -3/7}, or all whole numbers between 43 and 530, or multiples of 2, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
The set of counting numbers greater than one.
No. One, a counting number, doesn't belong to either of those sets.

There are 376740 such sets and you must think me crazy if you think I will list them all!
There are eight sets of 3 consecutive numbers in 12 hours.
You can make lots of sets that contain the number 74, for example:{74} {73, 74, 75} {0, 74, 8, 99} The set of integers The set of real numbers The set of complex numbers
