You can use any version using at maximum PHP 5.3 (XAMPP 1.7.7 and below).
Recommend stable versions are XAMPP 1.7.7, XAMPP 1.7.3 or XAMPP 1.7.1.
XAMPP 1.7.2 have had some issues.

Using the .zip version is recommend and if you don't register any windows services to start any of the XAMPP installation automatically, then yes you can have multiple XAMPP installations at the same time installed on the same computer (but cannot start them at the same time because they are configurated to use the same ports by default)
