Can I add more blocks in a View page?
In your view, under advanced there is a link called "Theme Information". If you open that up, there will be a list of all the different parts of the view that can be themed and a list of all the theme suggestions for each listed in order of broad to narrow.

You can create a theme file and naming it appropriately from the list of files in the theme information section. Once you've created the file, click on the "Rescan template files" button and the file you've created should be bold in the list.

Save the view and clear the cache.
