If the apps are on your computer's iTunes then connect your new iPad to your computer and select it on the left-hand sidebar of your computer's iTunes (if you are on iTunes 11 on your PC and the left-hand sidebar isn't showing then control-S should get it to appear), and then on the right-hand side use the Apps tab to select which of those apps to sync to the iPad.
