Five sounds like a lot for such a short essay. Whenever possible, you want to use details and anecdotes to illustrate your main point. (Which is difficult in such an unreasonably short essay!) If you can use one little story that shows off more than one trait, that will probably be best. You really don't want to end up with a laundry list of traits with no explanation, so go for depth over breadth and combining things where you can. Another way to do it is to name a few traits and then identify the most important and go into more detail about that one.
Depth >>>> breadth. It's not like adcoms will assume you lack a trait because you didn't mention it, so you don't need to mention everything. I know it sucks, but writing a few versions of the same essay is sometimes the easiest way to decide what works and what doesn't.
You have my sympathy. The questions this year are hard!
