public class Cursor : MonoBehaviour
{
public Texture2D cursor;
public int cursorSizeX = 16; // default
public int cursorSizeY = 16; // default

// Use this for initialization 
void Start () 
{ 
Object temp = Resources.Load("Textures/CR_Cursor (Custom)"); 

if (temp == null) 
Debug.Log("Load Object Fail"); 

cursor = (Texture2D)Resources.Load("Textures/CR_Cursor (Custom)"); 

if (cursor == null) 
Debug.Log("Load Cursor Fail"); 

Screen.showCursor = false; 
} 

// Update is called once per frame 
void Update () 
{ 
GUI.DrawTexture(new Rect(Event.current.mousePosition.x - cursorSizeX / 2, Event.current.mousePosition.y - cursorSizeY / 2, cursorSizeX, cursorSizeY), cursor); 
}

no matter where I instantiate the cursor im sill getting NullReferenceException: Object reference not set to an instance of an object
Cursor.Update (), what I am missing?

Just change your Update() method for OnGUI(). Unity uses this method to render all GUI mehtods such as the DrawTexture you use for your cursor.

void OnGUI()
{
    GUI.DrawTexture(new Rect(Event.current.mousePosition.x - cursorSizeX / 2, Event.current.mousePosition.y - cursorSizeY / 2, cursorSizeX, cursorSizeY), cursor);
}
