second question.. haha. Yeah you can write it any number of ways. One way would be Cm9add6add4addb9addb5(+11)(b13)/E5. That might actually be the longest chord name, but I don't think anything like that is indicated it music, since the (addb9, E5, and addb5) breaks the rules of a Cm9 chord. But the point is in writting a chord is be able to make sense of what you wrote.
