1) i believe that madam sharley only saw a sillouette of of luffy, i think it's possible as the strawhats become more famous, there will be more imposters of them much like the ones seen on shaboady archipeligo, and in fact, the person seen by madam sharley is in fact just one of these imposters (or a look a like) with a big ego, attacking one of the islands protected by luffy(which will occur in the future) to challenge him to see which one of them are truly worthy of the title strawhat, as the imposter tries to surpass the original

2)new ability i guess

3)should just be a df

4)im gonna guess they originate from around raftel,and the few that roll down in the water are the ones that float to other islands and eventually get eaten or sold

5)something embarassing about the founders of the world government which the government don't want found out or else it'll ruin the tenryubito's reputation; like  for example the founders of the world government all wore revealing clothes and were  okamas

6)im guessing some kind of giant air fortress :/

7)Dangerous weather i guess.. if that sign was there before akainu's and kuzan's fight it would have been blown to bits...
