Unfortunately not. Currently, you can only have one tab for each application per page. If you want to add several tabs on one page, you will need to have a separate application for each of them.
You can use different tabs for different pages from the same application using the profile_id property of the signed_request parameter. Check out the other properties of the signed_request parameter to learn more about how you can customize the contents of the page tab on the fly.
