Ok lets see...

Hitsugaya, Zaraki Kenpachi, Bykuya Kuchiki, Gin Ichimaru, Shunsui and Soifon are the ones I remeber.

I was too thinking about how they age in there, because they showed that kid who had died back in the war and he was still a kid 50 odd years later. But then it also showed Rukia grow up but it didn't seem long till she became an adult... HOWEVER was she actually born on Earth or the Soul Society? With the whole Sister thing it would seem like she was born that way so perhaps shes different. Also Renji is the same, does it hint anywhere whether he died on earth or was born there? Suppose being an Orphan you can't tell.
