            }
        }
    }

    if (fired)
    {
        timer += Time.deltaTime;
        if (timer > fireRate)
        {
            comboCount = 0;
            fired = false;
        }        
    }
}

Replace

if (comboCount == 2)

By

if (comboCount == 5)

If you want different animation for different combos, you can do:

if (comboCount > 1 && comboCont <= 5) {
    animation.Play("Combo" + comboCont);
}

var fired : boolean = false;
var comboCount : int = 0;
var fireRate : float = 3;
var timer : float = 0;

    function Update()
    {
        if (Input.GetKeyDown("u"))
        {
            if (!fired)
            {
                fired = true;
                timer = 0.0;
                comboCount = 1;
                Debug.Log("I served a punch!");
                //Do something awesome to deliver a punch!
                animation.Play("Combo1");
            }
            else
            {
                comboCount++;
                if if (comboCount > 1 && comboCont <= 5) {
    animation.Play("Combo" + comboCont);
}

                {
                    Debug.Log("I did a combo!");                
                    //Do something awesome for the combo!
                    animation.Play("Combo2");
                }
            }
        }


        if (fired)
        {
            timer += Time.deltaTime;
            if (timer > fireRate)
            {
                comboCount = 0;
                fired = false;
            }        
        }
    }
