While not a great coach, Mike Malone might be notable for the Kings because he could be added to this list: Eddie Jordan and Rick Adelman (2). That is the list of Kings head coaches that got another head coaching job after they left the Kings.
The remainder, whether head coach or interim head coach, never got another NBA head coaching job after they were finally done with the Kings (Reynolds twice): Phil Johnson, Jerry Reynolds, Bill Russell, Dick Motta, Rex Hughes, Gary St. Jean, Eric Musselman, Reggie Theus, Kenny Natt, Paul Westpahal, Keith Smart, Tyrone Corbin, and George Karl (13).
Some of those coaches are still fairly young and Karl just got here, but I feel fairly safe saying that say it’s unlikely anybody on that list is headed to another NBA head coaching job in the next 5-10 years (or probably ever).
