Passing More Then One Int Into Another Script As A GUI

I have a simple CubeManager script the allows me to set a certain cube into a CubeType, each with it's very own unique number from 0 - 9. What I'm trying to figure out and do is that when a cube is selected it would pass it's number value into another script to display as a GUI. How should I go about doing this? If I am correct the default cNumber way I set it up would cause confusing when passing numbers. (I have 10 cubes in my scene using the same script).

 using UnityEngine;
 using System.Collections;
 
 public class CubeManager : MonoBehaviour {
     
     public enum CubeType {cubeZero, cubeOne, cubeTwo, cubeThree, cubeFour, cubeFive, cubeSix,cubeSeven, cubeEight, cubeNine}
     
     public CubeType cubeNumType;
     public bool cubeClick = false;
     public int cNumber;
     public static int guiNum;
     
     public Material matCubeZero;
     public Material matCubeOne;
     public Material matCubeTwo;
     public Material matCubeThree;
     public Material matCubeFour;
     public Material matCubeFive;
     public Material matCubeSix;
     public Material matCubeSeven;
     public Material matCubeEight;
     public Material matCubeNine;
 
     void Start ()
     {
         CubeNum();
     }
     
     void Update ()
     {
         
         if(cubeClick)
         {
             renderer.material.color = Color.green;
             print (cNumber);
         }
         else
         {
             renderer.material.color = Color.white;    
         }
     }
     
     public void CubeNum()

                 guiNum = cNumber;

                 renderer.material = matCubeThree;

                 cNumber = 7;
                 break;
             case CubeType.cubeEight:
