Changing Apearence using Scripts

Hello. It's a little bit of a Complicated Question and I'm not sure if anyone can actually help me, maybe you just can't do what i want in unity(I think i can though which is why i'm asking here).

Here's what i got

1. I got 6 Character images

2. 4 Scripts controlling them

Here's what i have in Scripts

Reusable Controller for Each image

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class Wake : MonoBehaviour {
 
     public Image puciek;
     public int TargetAge;
     public int toohighAge;
     public AgeCounter aC;
     public FaceControll fC;
     public SleepCycle sC;
 
 
     void Update()
     {
         
         if (sC.awake == true) {
             if (aC.ageNum >= TargetAge && aC.ageNum <= toohighAge) {
                 puciek.enabled = true;
             } else 
             {
                 puciek.enabled = false;
             }
             fC.faceCycle = true;
         } else {
             if (sC.awake == false) {
                 puciek.enabled = false;
                 fC.faceCycle = false;
             }
         }
     }
 }
 
 

A sleep cycle that switches between a sleeping state and awake state of the Character

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class SleepCycle : MonoBehaviour {
 
     public FaceControll fC;
     public Wake wake;
     public Sleep sleep;    
     public int time;
     public float delay = 100.0f;
 
     public bool awake;
     private bool delayAdd;
 
     void Start ()
     {
         awake = true;
     }
 
     void Update ()
     {
         delay -= Time.deltaTime;
         if (awake) {
             sleep.image.enabled = false;
         } else {
         if (!awake) {
             sleep.image.enabled = true;
             }
         }
 
         if (delay > 50) {
             awake = true;
         } else {
             if (delay < 50) {
                 awake = false;
                 if (delay < 0) 
                 {
                     delay = 100;
                 }
             }
         }
     }
 }
 

Age Controll of the Character

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class AgeCounter : MonoBehaviour {
 
     public Text ageCount;
     public int ageNum = 0;
     public EXP experience;
     public int targetExp = 25;
 
     void FixedUpdate () 
     {
         if (experience.experiencePS >= targetExp) 
         {
             ageNum += 1;
             targetExp += 10;
         }
     }
 
     void Update()
     {
         ageCount.text = "Age: " + ageNum;
     }
 }
 

The Face controll is pretty simple so i'll leave it out, It just switches between 3 faces that are independent of the player character itself.

TheProblemitself I can't get the Character Images to SWITCH, all of them are on the screen at once, I don't want that. I could use a simple fix to my problem that doesn't include revising the whole Game system i built there .-.
