Page type restriction to root page

Hi,

  I need to apply page type restriction to root page structure.My cms site page root structure look like this:

   - Root

     -The Table

      -Home

       -Page 1

         -Page 2

          -Page 3

I want to restrict Page 1,page 2 with same page type and page 3 with another page type.Is it possible to implement in cms.

Thanks
