I would suggest one modification in your
Code:
on *:NICK:{
  if ($newnick == noiprocszzZZzz) { 
    timer-deop-pele 1 12 .mode #pele -o noiprocszzZZzz 
    timer-deop-one 1 14 .mode #one -o noiprocszzZZzz
    timer-deop-ikskile 1 16 .mode #ikskile -o noiprocszzZZzz
    timer-deop-secondsky 1 18 .mode #secondsky -o noiprocszzZZzz
    timer-deop-sviests 1 20 .mode #sviests -o noiprocszzZZzz
  }
}


If you assign a number to the timers, it might give a problem, since the timer could already be in use. If you just give it a name instead, the chance on that will be smaller.
