Most of them are surely canon, this is confirmed. However, we know that at least some of them might not be canon, which renders all of them not canon until further confirmation.

However, if you look at the tweet as a whole the message seems to be: "yes I think they are all canon, but I don't want to mess up, so I won't confirm it 100%"
