The set of integers is divided into three subsets. One is the positive integers. Another is the negative integers. The last subset has one element -- zero. In sum, integers are composed of the positive integers, the negative integers, and zero.
Yes, but greater than all negative integers
The sign of the product of four integers depends on the signs of the individual integers. There are 4 cases: 1) When all 4 integers share the same sign and all are non-zero (either all are positive or all are negative), the product is positive. 2) When 3 of the 4 integers share the same sign and all are non-zero (3 are positive and 1 is negative; or 3 are negative and 1 is positive), the product is negative. 3) When 2 of the integers are positive non-zero and the other 2 of the integers are negative non-zero, the product is positive. 4) If even one of the integers is zero, the product is zero (no sign - it is neither positive nor negative).

The set of positive integers contains 1 but not zero. Within the set of integers, there is the subset of positive integers, the subset of negative integers and the subset with a single element in it - zero. There are a zillion other sets that could be specified that meet the conditions set down in the question. The one cited is an easy one.
The integers are the numbers {0, 1, 2, 3, ...} and the numbers {-1, -2, -3, 4, ...}. That is, they are all of the "whole" numbers, their negatives, and zero. A non-zero integer is any integer except 0.
Yes, by definition all positive integers are whole numbers.
Zero is a an integer and, since all integers are real numbers, zero is a real number.
Most people refer to the positive integers as the natural numbers. That would exclude the negative integers and zero.
none
All of the natural numbers and zero are called integers.
The set of integers includes negative integers as well as positive integers. It also includes the number zero which is neither negative nor positive.
The average is zero.
