Yes it is. That is the definition of rational numebrs.
No.The definition of a rational number is a number that can be written as the quotient of two integers (and the divisor is not zero).The definition of an irrational number is a real number that cannot be written as the quotient of two integers (and the divisor is not zero).A number can either be written as the quotient of two integers or it can't. One or the other.A number cannot be both rational and irrational.
Rational
A quotient of two numbers cannot have a denominator which is zero: such a fraction is not defined.

None. A rational number is a number that can be written as the quotient of two integers where the divisor is not zero. An irrational number is a real number that cannot be written as the quotient of two integers where the divisor is not zero. Any given real number either can or cannot be written as the quotient of two integers. If it can, it is rational. If it cannot, it is irrational. You can't be both at the same time. The square root of -1 is not a real number and it cannot be written as the quotient of two integers, so it is neither rational nor irrational.
No, it is not necessary for both numbers to be integers for their quotient to be an integer. For example, if you divide a rational number by another rational number that shares a common factor, the result can still be an integer. For instance, ( \frac{4.0}{2.0} = 2 ), where both numbers are not integers but the quotient is an integer. However, if both numbers are integers, their quotient will also be an integer if the numerator is divisible by the denominator.
