Take notice: The HBs have always had late donations of additional titles (sometimes after you can no longer donate for them). There are 5 blank spots on the 'Android App screen' in the mock picture so I'm gonna guess and say there will be more added to this time around too.
To attempt to fix a broken download:
Reboot your device
Go into Market
Tap Menu
Tap My Apps
Tap on Download or Update for the Apps to install
Note: It may be a problem with installing 3rd party Apps so make sure that in Settings - Applications Install from unknown sources is checked.
If you mean the image at the top of the page, I only see three spaces, and it's a mock-up of the pattern unlock screen which always has those nine spaces, but it's still possible, I suppose.
As for the Market, because of the way it works (currently), because they weren't downloaded from the Market itself it won't authorise an update from it; you'll have to update it manually, most likely from the page you originally used. I think Reddit suggested the possibility of an Humble app, which if true could make future updates easier.
