Having different site contents

Hi can anyone tell me how can I have different site page contents for all my pages?
Say my website is http://www.elevendwind.com/wp/ (home page) and other sites are http://www.elevendwind.com/wp/test2/ and http://www.elevendwind.com/wp/test3.

They will be using different files say file1.php, file2.php & file3.php respectively.

I realise that I have to make some changes to the front-page.php section but not sure what to be done.
