Air comand can be flashed from here, and it has similarity with Note 4. i didnt sow difference between N4 and N5 commands exept it designe and button (on our Note 2 at least). Personaly, im using these:

and if U dont like it, just reflash Rom without wiping data. Do not forget to wipe Dalvick and Cache before and after flashing from recovery. And use Trimmer(fstrim) for better Rom performace(also cache cleaner and narive Ram - memory cleaner) . Do Nandroid backup first!

yes, wipe system and if u must to save data, save it in recovery like backup... Than, if there is problems, do clear data and cache in apps with problems and- do fix permissions(best from latest TWRP). Reboot and enjoy it.
