Yes, there are more real numbers than integers. The set of integers is countable, meaning its elements can be listed in a sequence. In contrast, the set of real numbers is uncountable; there are infinitely many real numbers between any two integers, as shown by Cantor's diagonal argument. Thus, the cardinality of the real numbers is strictly greater than that of the integers.
They are all numbers
You have it backwards. Integers are a subset of real numbers.
There is no such thing as consecutive numbers because numbers are infinitely dense. Between any two numbers there is another and so there is no such thing as a "next" number.There are no integers (square or non-square) between any two consecutive integers. There are infinitely many numbers between any two consecutive integers and, if the integers are non-negative, every one of these will be a square of some number so the answer is none. If the integers are negative then the infinitely many numbers will have a square root in the complex field but not in real numbers. In this case the answer is either none or infinitely many, depending on the domain.
The density property does not hold for odd numbers in the same way it does for the set of all integers or real numbers. While there are infinitely many odd numbers, they are not densely packed within the integers; there are gaps between them (specifically, every even integer separates two odd integers). Thus, between any two odd numbers, there are even integers, indicating that odd numbers do not form a dense subset of the integers.
yesYes, integers are real numbers.
All integers are real numbers, but not all real numbers are integers.
No, all integers are real numbers, but not all real numbers are integers. For example, 1.25 is a real number and a non-integer.No.

Rational numbers and Real Numbers. The multiplicative inverses of integers are not integers.

Natural numbers Integers Rational numbers Real numbers Complex numbers
Natural numbers = Whole numbers are a subset of integers (not intrgers!) which are a subset of rational numbers. Rational numbers and irrational number, together, comprise real numbers.
Decimals are real numbers. Furthermore, integers and whole numbers are the same thing.
