Not necessarily. The sum of two irrational numbers can be rational or irrational.
Two is an integer. All integers are rational numbers.
Yes, you can.
No, -5 is not an irrational number. Irrational numbers are numbers that cannot be represented as the quotient of two integers. Since -5 is already an integer, it is rational.
Yes. The sum of two irrational numbers can be rational, or irrational.

Two is an integer. All integers are rational numbers.
Yes - if I had an irrational number x, and I added that to the number (7-x), I would end up with 7.If the number is irrational, it can be subtracted from a rational/integer to make another irrational.
Yes, you can.

Yes. The sum of two irrational numbers can be rational, or irrational.
No irrational numbers are integers. Pi is one example.
Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.
no
Sure; for example, 10 + pi is irrational, 10 - pi is irrational. Both are positive. If you add them, you get 20.
1 is rational. Rational numbers are numbers that can be written as a fraction. Irrational Numbers cannot be expressed as a fraction.
No, integers aren't irrational numbers. For a number to be irrational, it must not be able to be expressed as a fraction of two integers. Every integer can be expressed as the integer itself divided by one, and so fails to meet this requirement. For example, 2 can be expressed as 2/1; therefore, it is a rational number as opposed to an irrational number.
