A single hand, several handwritings

[Koen G]

Cheating would actually take more effort than giving it an honest try. I'd say the different ones are, in the order I'm noticing them:

• 9: slant, like the "s" in "Est"
  
• 4: several completely different letters like middle-word -g-, final -s.
  
• 0: tricky because it's more tidy, which doesn't mean different scribe. Still, I see differences in several letters like the various s-shapes.
  
• 7: again tricky since it's a different layout but I see differences in a number of letters, even small "e".
  
• 3: definitely different in a number of letters, though it might be a "quicker" hand
  

That leaves 1,2,5,6,8 as the same hand, although there are some differences between them. But that's my guess.

It's harder than I thought. Ideally I would look for larger samples and search for the same word (esse, sunt...). That should make it a bit easier. 
I wouldn't be surprised if I got them all wrong, but you won't learn anything if you're not willing to make a fool of yourself
