Christoph Letkowski is collecting Instagram usernames like Pokemon cards.
The first 3 accounts are created and run by him, 100% sure.
The other ones....well my guess is that the "fanpage" one also was created by him. And the one called "kriztowski" -same as his Facebook account- could also be him.
Why creating so many accounts ? I have a theory: I think he's paranoid, and to prevent me or anyone else to use his name in any social platform, he's creating these imaginary walls, so that no one can create an account with usernames he has already used in other platforms (such as lette1606 on eBay).
