  Am I allowed to do the following using "variables" extension:

no.

  If the answer is yes, two more questions:
  1). How do we expand integer variables inside strings?
  2). Can a variable get a string value after it was assigned an integer
  value?

the problem is rather that the variable can only be expanded inside a
string, so it would lose its integer property.

Which is fine, as long as this is documented.
I believe the current document doesn't specify what types of variables are
allowed.
You have to either explicitly allow or prohibit this.

do you have a use for integer variables?

You already have the "length" function. I was thinking something along the
lines of comparing lengths/counting headers/scoring.
However this will probably require some actions for simple arithmetic (+/-).
