Not so much as would they need to be run in a raceway but what is the required wiring method. I doubt any would have to be run in raceway if the correct wiring is used.
Even with raceway you will have to determine whether these circuits are CL1, 2 or 3 and proceed from there. If any are CL1 you may not be able to use the wire you have even with raceway.
