Hi guys i manged to make one way point that is attached to a target and it tells the distance between the target and the player

Now im trying to add 5 more and thats what i cant figure out. So im trying to make 6 way points with each target telling the player the distance between the player and target

This is my code

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

public class Waypoint : MonoBehaviour

{

private Image iconImg;

private Text distanceText;

public Transform Player;
public Transform Target;
public Camera Camera;

public float closeDistance;

// Update is called once per frame
private void Start()
{
    iconImg = GetComponent<Image>();
    distanceText = GetComponentInChildren<Text>();
}

private void Update()
{
    if(Target != null)
    {
        GetDistance();
        CheckOnScreen();
    }
}

private void GetDistance()
{
    float dist = Vector3.Distance(Player.position, Target.position);
    distanceText.text = dist.ToString("f1") + "m";
    
    if(dist < closeDistance)
    {
        Destroy(gameObject);
    }

}

private void CheckOnScreen()
{
    float thing = Vector3.Dot((Target.position - Camera.transform.position).normalized, Camera.transform.forward);

    if(thing <= 0)
    {
        ToggleUI(false);
    }
    else
    {
        ToggleUI(true);
        transform.position = Camera.WorldToScreenPoint(Target.position);
    }
}

private void ToggleUI(bool _value)
{
    iconImg.enabled = _value;
    distanceText.enabled = _value;
}

}

Thanks in advance

Make an Array of GameObjects for your targets

public Transform[] Target = new Transform[6];  //Make an Array for your targets 
 public Camera Camera;
 public float closeDistance;
 // Update is called once per frame
 private void Start()
 {
     iconImg = GetComponent<Image>();
     distanceText = GetComponentInChildren<Text>();
 }
 private void Update()
 {
int targetCounter = 0;  //Loop through the Array and check if Transform is not null
foreach(var target in Target){
if(target != null){
targetCounter++;
}
}
     if(targetCounter > 0)  //Check if Array is larger than 0
     {
         GetDistance();
         CheckOnScreen();
     } else {
     Debug.Log("No more targets");   //Array Length is 0
  }
 }
 private void GetDistance()
 {
foreach(var target in Target){  //Loop through the Array and check distance tothe waypoints
     float dist = Vector3.Distance(Player.position, target.position);
     distanceText.text = dist.ToString("f1") + "m";
     
     if(dist < closeDistance)
     {
         Destroy(gameObject); //If you want to remove the waypoints instead of the gameobject you have to set target to null
     }
 }
}

 private void CheckOnScreen()
 {
foreach(var target in Target){ //Loop through the array and check if target is on screen
     float thing = Vector3.Dot((target.position - Camera.transform.position).normalized, Camera.transform.forward);
     if(thing <= 0)
     {
         ToggleUI(false);
     }
     else
     {
         ToggleUI(true);
         transform.position = Camera.WorldToScreenPoint(target.position);
     }
 }
}

 private void ToggleUI(bool _value)
 {
     iconImg.enabled = _value;
     distanceText.enabled = _value;
 }
}
