Adding Names

Ok so i have this generator that will spawn a random prefab with random stuff. I just cant work out how to add "text" to the strings. So to add a list of names. E.G Bob, Frank and Dave. (i'm also struggling with how to update the GUI as well)

 var enemyPrefabs : GameObject[]; // Array of different Enemies that are used.
 var spawnPoints : Transform[];  // Array of spawn points to be used.
 var Name1Choices : String[]; //how do i store names here: e.g Bob, frank, dave
 var Name2Choices : String[];
 var Backstory1Choices : String[];
 var Backstory2Choices : String[];
 var Backstory3Choices : String[];
 var Name1;
 var Name2;
 var Backstory1;
 var Backstory2;
 var Backstory3;
  
 var mission : boolean = false;
 var money : float;
  
 function Start () 
 {
     MissionGen();
 }
  
 function MissionGen () 
 {
     if( !mission )
     {
        var pos :  Transform = spawnPoints[Random.Range(0, spawnPoints.length)];  // Randomize the spawnPoints to instantiate enemy at next.
        var obj : GameObject = enemyPrefabs[Random.Range(0, enemyPrefabs.length)];
        Instantiate(obj, pos.position, pos.rotation); 
  
            Name1 = Name1Choices[ Random.Range( 0, Name1Choices.length ) ]; //Randomly Generated Name
           Name2 = Name2Choices[ Random.Range( 0, Name2Choices.length ) ]; //Randomly Generated Name Part 2
            Backstory1 = Backstory1Choices[ Random.Range( 0, Backstory1Choices.length ) ]; //Randomly Generated BackStory Part 1
            Backstory2 = Backstory2Choices[ Random.Range( 0, Backstory2Choices.length ) ]; //Randomly Generated Backstroy Part 2
           Backstory3 = Backstory3Choices[ Random.Range( 0, Backstory3Choices.length ) ]; //Randomly Generated Backstory Part 3
            mission = true;
            GameObject.Find("Name1").guiText.text = Name1;
     }
     else
     {
        Invoke( "MissionGen", 30.0f );
     }
 }
  
 function Check () 
 {
     var BadGuyCheck : GameObject = GameObject.FindGameObjectWithTag( "BadGuy" );
     if ( BadGuyCheck == null )
     {
        mission = false;
        money += Random.Range(1000,10000);
        yield WaitForSeconds (30);
        Invoke( "MissionGen", 30.0f );
     }
 }
