Doubt 1
Is it possible to use same variable name for multiple values ?

Variables can store only 1 value at a time. If you store new value to a variable, value of variable changes to that new value.

Doubt 2
Is variable name is case sensitive ?

I mean both the following variables will give different values in the same script ?

Variables are case sensitive.
