Question: where are the khajiit in whiterun?
Answer: There are three groups of Khajiit traders that travel between the cities of Skyrim. You'll have encountered Ri'saad's band outside Whiterun, and may find him again near Markarth; the others (led by Ahkari and Ma'dran) can be found between Riften and Dawnstar, and between Windhelm and Solitude, respectively.
