Use a script more than once?

Hello Unity3D i have a question about using the same script for more than one character?Is it possible to use the same script for more than one player?the reason why i ask this question is the fact that i have more than one character that needs to do combos and so far i only got one character to do so but i want another one to do it as well.If anyone know i can fix this problem.Can you please tell me how can i?

Script if anyone was wondering #pragma strict

 var combos : combosequence[] = new combosequence[3]; //Combo class. Fill this out in Inspector.
 var comboMaxTime : float = 1.0; //How long a timer for combo lasts in seconds. Fill this out in Inspector.
 var comboSpanTime : float = .25; //The span of when a combo can start. Fill this out in Inspector.
 var comboMidPoint : float = .5; //The position within the maxtime of a combo the span is active. Fill this out in Inspector.
 private var currentCombo : int = -1;
 private var comboTimeout : float = .0;
 AudioListener.volume = 100;
  
 function Update () {
     if (Input.GetKeyDown("u")) Attack();
     if (comboTimeout > 0) DecreaseTime();
 }
  
 function Attack () {
     ComboTime(); //Do all the logic for timing before animation etc.
     animation.Play(combos[currentCombo].comboAnimation); //Play the currentCombo combos' animation
     audio.clip = combos[currentCombo].comboSound; //Set the audio clip to the currentCombo combos' audio
     audio.Play(); //Finally play the audio
     audio.volume = 50;
  
     //Add logic for hitting enemies etc here!
  
 }
  
 function ComboTime () {
     if (currentCombo<combos.Length-1 && 
             comboTimeout>0 && 
             comboTimeout>comboMidPoint-comboSpanTime &&
             comboTimeout<comboMidPoint+comboSpanTime ||
             currentCombo==-1) {
             currentCombo++;
     } else {
         currentCombo = -1;
     }
     comboTimeout = comboMaxTime;
 }
  
 function DecreaseTime () {
     comboTimeout-=1*Time.deltaTime;
 }
  
 class ComboSequence {
     var comboName : String; //A name for current attack (might be of use later for tutorial or something else)
     var comboAnimation : String; //The animation name for current attack
     var comboSound : AudioClip; //The audio for current attack
