The only exception is the personal name Barqos, “Qos gleamed forth” (Ezra 2:53; Nehemiah 7:55). The name Kushaiah (1 Chronicles 15:17) has the variant form Kishi in 1 Chronicles 6:29 (6:44, English) and in any case involves a spelling with shin that is never used for Qos in other texts. See E.A. Knauf, “Qôs,” in Karel van der Toorn, Bob Becking and Pieter W. van der Horst, eds., Dictionary of Deities and Demons in the Bible, 2nd ed. (Grand Rapids, MI: Eerdmans, 1999), p. 674.
