I repotted my Cleopatra-Denorbrium and I sepperated it at the root base, It had 5 canes and each one seemed to have a viable root system. I sepperated it into 2 plants. Did I do right or did I kiil it?

Also I have an orchid (unknown name) which lost all folliage. I does not show any new leaf formation but the canes are still green under the white dry outter layer. Is it still alive and will it form new leaves/blooms???
