How to use list to add new items & function?

Hi Guys,

I'm trying to use generic list in javascript or unityscript to: 1) add new timer in the game scene live itself 2) add new, edit & store each player's personal gold or money

My questions:
1a) how do I add new item to my list in the game scene live?

 myList.Add(theItem);   // add an item to the end of the List
 myList[i] = newItem;   // change the value in the List at position i

1b) I know above coding is how it works, but I don't know how to apply it to my coding in this case. Could I have a few examples of applying to the my own generic coding below?

2) how do I dynamically add the timer function in the game scene live again? For instance each time a button is press or a player game, a new timer is assign and calculate by itself.
Currently, I can hard code like a few timers in the script by itself. But if I wish more timers, then it will be too messy, so I would like to be able to dynamically add new timer and count the timer.

3) How to remove, and edit the value in my 2 generic list, `differentPlayerGold` & `timerList`?

Below is my Generic List coding:

 #pragma strict
 import System.Collections.Generic;
 class Timer
 {
      var timerCounter : float = 0;
     var timerMax : float = 5.5;
     var timerActive : boolean = false ;
 }
 var differentPlayerGold : List.<int> = new List.<int>(); // Store each player's gold
 var timerList = new List.<Timer>(); // store different player's time limits
 
 function Start () 
 {
   differentPlayerGold.Add(5);
   differentPlayerGold.Add(7);
 }
 
 function Update () 
 {
     Debug.Log(differentPlayerGold);
 }

I read some of the links provided & previously ask questions. But I don't get it.

Below is my current Timer coding:

 #pragma strict
 class TimerClass 
 {
    var FirstTimer : float = 0 ;
    var FirstTimerActive : boolean = false ;
    var SecondTimer : float = 0 ;
    var SecondTimerActive = true ;
    
    var FirstTimerTime : float;
 }
 var PlayerTimer : TimerClass = new TimerClass ( ) ;
 //or 
 //var PlayerTimer = new TimerClass ( ) ;
 //var PlayerTimer : TimerClass2 ;
 
 function Awake ()
 {
     PlayerTimer.FirstTimerTime = PlayerTimer.FirstTimer;
 }
 
 
 function Update ( )
 {
 //    Debug.Log(PlayerTimer.FirstTimerActive);
 //    Debug.Log (PlayerTimer.FirstTimer);
 
 }
 function OnGUI ()
 {
 
    if ( PlayerTimer.FirstTimerActive )
    {
      PlayerTimer.FirstTimer -= 1 * Time.deltaTime ;
       if ( GUI.Button(Rect(50, 150, 100,30), "PAUSE"))
       {
          PlayerTimer.FirstTimerActive = false ;
       }
       GUI.Box (Rect (160, 150, 100,30), "UNPAUSE");
    }
    
    if ( !PlayerTimer.FirstTimerActive && PlayerTimer.FirstTimerTime != PlayerTimer.FirstTimer)
       {
       if( GUI.Button(Rect(160, 150, 100,30), "Resume"))
       {
          PlayerTimer.FirstTimerActive = true ;
       }
       GUI.Box (Rect (50, 150, 100,30), "PAUSE");
 
    }
    
    
    
 // 2ND TIMER
 //   if ( PlayerTimer.SecondTimerActive ){
 //      PlayerTimer.SecondTimer -= 1 * Time.deltaTime ;
 //      if ( GUI.Button(Rect(150, 150, 100,30), "PAUSE2")){
 //         PlayerTimer.SecondTimerActive = false ;
 //      }
 //   }else{
 //      if( GUI.Button(Rect(200, 150, 100,30), "Resume2") )
 //      {
 //         PlayerTimer.SecondTimerActive = true ;
 //      }
 //   }
 
         // stop button  timer 1
     if (!PlayerTimer.FirstTimerActive && PlayerTimer.FirstTimer == PlayerTimer.FirstTimerTime )
     { 
         if (GUI.Button(Rect (50, 100, 210,30), "START"))
         {
             PlayerTimer.FirstTimerActive = true ;
         }
         GUI.Box (Rect (50, 150, 100,30), "PAUSE");
         GUI.Box (Rect (160, 150, 100,30), "UNPAUSE");
     }
     
     //reset button timer 1
       if (PlayerTimer.FirstTimer != PlayerTimer.FirstTimerTime )
     { 
         if (GUI.Button(Rect (50, 100, 210,30), "RESET"))
         {
             PlayerTimer.FirstTimerActive = false ;
             PlayerTimer.FirstTimer = PlayerTimer.FirstTimerTime;
         }
     }
     
 }

I have yet combine, I didn't combine so that it won't be so messy and easier to understand.
Please let me know if I need to provide anything more, thanks!
