I would think high millions to low billions, lots in Craftworlds maybe around 30-60 million on one, Exodites 1-10 million a world, Dark Eldar in Commorragh 100 million to 10 billion, I am being generous with my numbers. If the Dark Eldar are using reproduction vats it would allow much bigger numbers to been grown at one time.

My guess is those can grow someone to maturity in around a year or two give or take a few mouths for a human (a human takes 18-20 years to grow to maturity), and a Eldar around three-four years (they seemly more complex and live longer than a human, such cells can not be "flash grown" of a would maybe damage the cells, making defects and deformities.
