I’ve got this code for it to shoot:

 using UnityEngine;
    using System.Collections;
    
    public class controleBalaC : MonoBehaviour {
    	
    	public Transform ballCannon;
    	public float forceShot;
    	
    	private Transform pointShot;
    		
    	// Use this for initialization
    	void Start () {
    		pointShot = transform.Find("Shooter");
    		
    		
    		
    	
    	}
    	
    	// Update is called once per frame
    	void Update () {	
    			Transform instancia = (Transform) Instantiate(ballCannon, pointShot.position, pointShot.rotation);
    			instancia.rigidbody.AddForce(pointShot.TransformDirection(Vector3.forward) * forceShot);
    		
    	
    }
    	       
    }

But I want him to shoot yourself every 5 seconds.
You can do this?

using UnityEngine;
using System.Collections;

public class controleBalaC : MonoBehaviour {

    public Transform ballCannon;
    public float forceShot;

    private Transform pointShot;

    // Use this for initialization
    void Start () {
       pointShot = transform.Find("Shooter");

    }

    float lastTime = 0;
    // Update is called once per frame
    void Update () {   
         if(Time.time - lastTime >= 5)
         {
              Transform instancia = (Transform) Instantiate(ballCannon, pointShot.position, pointShot.rotation);
              instancia.rigidbody.AddForce(pointShot.TransformDirection(Vector3.forward) * forceShot);
              lastTime = Time.time;
          }

}

}
