how in order to pursue many targets?

he will pursue the object with the tag "Enemy" (coins) and if he meets the coins, the coins will disappear and he will pursue other coins?

my script single target :

 using UnityEngine;
 using System.Collections;
 
 public class AICharacterBehaviour : MonoBehaviour {
     public GameObject target; 
     public float movingSpeed = 2f; 
     public float turnSpeed = 0.05f; 
 
     void Update() {
         Vector3 gapPosition = target.transform.position - this.transform.position; 
         gapPosition = new Vector3(gapPosition.x, 0, gapPosition.z); 
         Quaternion lookRotation = Quaternion.LookRotation(gapPosition); 
         this.transform.rotation = Quaternion.Lerp(this.transform.rotation, lookRotation, turnSpeed); 
 
         this.transform.Translate(Vector3.forward * movingSpeed * Time.deltaTime); 
     }
 }
