I probably overlooked this, but what did Rand do with the angreals from Rhuidean?

 

The stash of ter'angreal are still stored away somewhere in Cairhien.

I take you mean the terangreals.  To my knowledge, there was not sa'angreal or angreal from there.

Like another poster told, they are somewhere in Cairhien.  I would guess in a warehouse; possibly Rand warded the warehouse after the items were stored in it.
