What is pi called i.e what type of variable?
Pi is not a variable. Pi is an irrational real positive number. The value of pi is approximately 3.14159 irrational means there is no way to write the exact value of pi. It can not be written with a finite number of decimal points. It can not be written as a fraction. it can not be written as the nth root of any number. real means it is not generated by taking the square root of a negative number and it is not generated by dividing anything by 0 . positive means it is greater then 0.

Can we include irrational numbers in the set of positive numbers?
Yes, any positive number is a number that doesn't have a (-) behind it (-20; -23.67; -45.45454...), and is not zero (0). Any repeating number (see 3rd negative example) is irrational, no matter what its sign. Irrational numbers also include numbers (decimals, specifically) that don't repeat, but don't stop. Numbers that don't terminate include pi. Pi, as it is, is proof of a positive irrational number.
