Collab puzzle

The final link you're looking for will be a puush link of this form: http://puu.sh/bPTGy/da4a72449c.jpg
The final link also starts with b, and every letter after the first five is lowercase.
The links below are separate puzzles, each of which will give you two characters for the link (not including the first b). The seven raffles aren't in order. I wonder what the order could be?
The raffles run for a week (so there's plenty of time for you to get absolutely sick of the number 7).

Here are the links:
