How to make spawned in game objects pause with mouse click.

Hi, Ive got three columns spawning in and I want one column to pause for 5 seconds when i use GetMouseButtonDown. Any help would be amazing! Thanks.

These are the three columns of squares spawning in:

this is my main script:

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

public class Main : MonoBehaviour {

 public static float Range;

 

 public GameObject[] squaresDownArray;
 public GameObject[] squaresUpArray;
 public GameObject square;


 int index;

 public Color[] colourArray;


 public Vector2 leftSpawnPosition;
 public Vector2 midSpawnPosition;
 public Vector2 rightSpawnPosition;

 public float spawnTimer;
 private float spawnCounter;

 private int squareIndexCounter;



 // Use this for initialization
 void Start () {



 


     
     //squaresDownArray = GameObject.FindGameObjectsWithTag ("SquareDown");
     //squaresUpArray = GameObject.FindGameObjectsWithTag ("SquareUp");


     InvokeRepeating ("TimerTick", 0, 1);

 }
 
 // Update is called once per frame
 void Update () {
     spawnCounter += Time.deltaTime;



     
 }


         public void TimerTick(){
     
     if(spawnCounter >= spawnTimer){
     GameObject lSquare = Instantiate (square, leftSpawnPosition, Quaternion.identity);
     lSquare.tag = "SquareDown";
         //lSquare.GetComponent<SpriteRenderer> ().color = colourArray [squareIndexCounter];
         lSquare.GetComponent<MeshRenderer>().materials[0].color = colourArray[Random.Range(0,colourArray.Length)];

         squareIndexCounter++;
         if (squareIndexCounter >= colourArray.Length) {
             squareIndexCounter = 0;
         }

     GameObject mSquare = Instantiate (square, midSpawnPosition, Quaternion.identity);
     mSquare.tag = "SquareUp";
         //mSquare.GetComponent<SpriteRenderer> ().color = colourArray [squareIndexCounter];
         mSquare.GetComponent<MeshRenderer>().materials[0].color = colourArray[Random.Range(0,colourArray.Length)];




     squareIndexCounter++;
         if (squareIndexCounter >= colourArray.Length) {
             squareIndexCounter = 0;
         }

     GameObject rSquare = Instantiate (square, rightSpawnPosition, Quaternion.identity);
     rSquare.tag = "SquareDown";
         //rSquare.GetComponent<SpriteRenderer> ().color = colourArray [squareIndexCounter];
         rSquare.GetComponent<MeshRenderer>().materials[0].color = colourArray[Random.Range(0,colourArray.Length)];



             //[squareIndexCounter];



         squareIndexCounter++;
         if (squareIndexCounter >= colourArray.Length) {
             squareIndexCounter = 0;
         }
         spawnCounter -= spawnTimer;
     } 

     foreach (GameObject square in GameObject.FindGameObjectsWithTag("SquareUp")) {
         square.GetComponent<SquareScript> ().Move ("up");




     }
     foreach (GameObject square in GameObject.FindGameObjectsWithTag("SquareDown")) {
         square.GetComponent<SquareScript> ().Move ("down");


     }



         


 }

}

this is my script for my squares:

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

public class SquareScript : MonoBehaviour {

 public float moveSpeed;
 private float moveTimeCounter;
 public float moveDistance;
 private Vector3 endPos;

 private float averageDTime;
 private int averageDTCounter;
 private bool moving;

 Main Main;

 // Use this for initialization
 void Start () {
     Main = Main.GetComponent<Main> () as Main;

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

     if (Input.GetMouseButton (0)) {
         moving = false;
     }



     if (transform.position.y > 8 || transform.position.y < -8) {
         Destroy (gameObject);
     }

     if (moving) {
         
         if (moveTimeCounter <= 1) {
             moveTimeCounter += Time.deltaTime * moveSpeed;
             averageDTime += Time.deltaTime;
             averageDTCounter++;
         } else {
             moveTimeCounter = 0;
             moving = false;
             print (averageDTime / averageDTCounter);
             averageDTCounter = 0;
             averageDTime = 0;
         }
         transform.position = Vector3.Lerp (transform.position, endPos, moveTimeCounter);
     }
 }

 public void Move(string moveDirection){
     moving = true;
     if (moveDirection == "up") {
          endPos = new Vector3 (transform.position.x, transform.position.y + moveDistance, 0);
     }
     if (moveDirection == "down") {
         endPos = new Vector3 (transform.position.x, transform.position.y - moveDistance, 0);
     }

 }
     

}

and this is the mouse down script:

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

public class ClickScript : MonoBehaviour {

 public float speed = 0.1F;

 // Use this for initialization
 void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {

     if (Input.GetMouseButtonDown (0))
         Debug.Log ("Pressed left click.");

     if (Input.GetMouseButtonDown (1))
         Debug.Log ("Pressed right click.");

     if (Input.GetMouseButtonDown (2))
         Debug.Log ("Pressed middle click.");



     if (Input.touchCount > 0 && Input.GetTouch (0).phase == TouchPhase.Moved) {
         // Get movement of the finger since last frame
         Vector2 touchDeltaPosition = Input.GetTouch (0).deltaPosition;

         // Move object across XY plane
         transform.Translate (-touchDeltaPosition.x * speed, -touchDeltaPosition.y * speed, 0);
         Debug.Log ("swipe.");
 
     }


 }

 }
