Other servitors in Yaqub's lair

There are 10 boys who serve in Yaqub's lair, 5 attached to Hakim, who was in charge of the pantry, kitchen, and garment workshop, and 5 attached to Nuri, who oversaw the residential quarters of Yaqub's concubines and other captives. All were apparently sired by Yaqub, and more bore a resemblance to his human form and their brothers or half-brothers.
It is not clear whether they possess magical powers or not, but if they do, they have not yet used it.
They are all still alive, in Yaqub's lair.
They appear in chapters 19, 20 and 21.
