Depends really. There is a lot you could do I suppose.

Tornados, hurricanes, razor wind, vacuum, flight, etc. Depends just how strong the Level 5 is, thet persons creativity with their powers, and exactly how their power has manifested.

The only confirmed wind user is Kongo

Spoiler for kongo:

(Aero Hand) who could create blasts of air strong enough to throw a truck into a helicoptor where ever she touched at Level 4.

Not really much of reference.
