Disable cubes


Please i’m in trouble i have this cubes, but I need that when I press over one the rest must be deactivated, For example if I press “ch” the rest must be desactivated except the “Siguiente” text.

There is a part of the Script that I use:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ChadoScript : MonoBehaviour {

//public GameObject cubes;
// Use this for initialization
public int scoreAmount = 0;
public string letra = "";
int scorePP=0;
int scoreFinal=0;
//string arr = new string [] {"A"};
void Start () 


// Update is called once per frame
void Update () 

	if (Input.GetMouseButtonDown(0))
		Ray ray = GetComponent<Camera>().ScreenPointToRay(Input.mousePosition);
		RaycastHit hit;
		if (Physics.Raycast(ray, out hit))

		if (hit.collider.tag == "Letra_ch")
			if (GameManager.gm) {
				GameManager.gm.targetHit (scoreAmount);
			scoreFinal= PlayerPrefs.GetInt ("Score", scorePP)+scoreAmount;
			PlayerPrefs.SetInt ("Score", scoreFinal);
			Debug.Log ("Score en ch: " + scoreFinal);
			Debug.Log ("ESTOY EN CH EN SCRIPT: " + letra);
			PlayerPrefs.SetString ("Chado", letra.ToString());
