I would only ED if you have a clear first choice school and it is affordable.
I think you are an outstanding student and have wonderful ECs- congrats! Given you have safeties and targets, you are free to apply to all of these schools- but understand that they are all reaches and it is not possible to chance you.
UNC has a secondary admission to their business school, but there are students who are accepted right away. It is a reach due to OOS caps. Pay attention to the essays and what you would contribute to the school and community.
Good luck!
