How to choose certain objects within tagged objects?

Unity Engine

Hello, so I am trying to make a menu, lets say it has 5 different boxes in it. Each of these boxes is connected to a character, and when this character dies, I want the box to be deleted, this is working fine. However lets say character 3 is killed, I want box 4 and 5 to shift up to fill in the gap, currently I am only able to make it so that all of the boxes move up, does anyone know how to solve this? Here’s what I’m working with:

 using UnityEngine;
using System.Collections;

public class Game_Sorting : MonoBehaviour
{

    private GameObject[] menu;
    private GameObject[] selected;

    void OnDestroy()
    {
        menu = GameObject.FindGameObjectsWithTag("SurvivoursMenu");
        foreach (GameObject om in menu)
        {
            if (gameObject.transform.position.y <= om.transform.position.y)
            {
                om.transform.position = new Vector3(om.transform.position.x, om.transform.position.y + 45, 0);
            }
        }
    }
}

The first method that I can think of (what you can see me trying to implement in the script) is making all boxes with a lower y value of the box being destroyed shift up, but this either makes them all move up or nothing move up, depending on the “>”, and I don’t seem to be able to add this to GameObject[ ] list. Another method I was thinking was giving each one a spawn number, e.g box one = 1, box two = 2, so on, but I don’t know how to implement this yet. Any advice or links of where to go to would be great, I can’t seem to find anything about this online.

Update: I have solved this issue, by implementing a count system, making only the objects that have a lower number than that deleted move down, below is my solution, please message me if need any help.

using UnityEngine;
using System.Collections;

public class Game_Sorting : MonoBehaviour
{
    private GameObject[] menu;
    public int start = 0;
  
    void Start()
    {
        menu = GameObject.FindGameObjectsWithTag("SurvivoursMenu");
        foreach (GameObject om in menu)
        {
            start = om.GetComponent<Game_Sorting>().start++;
           
        }
    }

    void OnDestroy()
    {
        menu = GameObject.FindGameObjectsWithTag("SurvivoursMenu");
        foreach (GameObject om in menu)
        {
            if (gameObject.GetComponent<Game_Sorting>().start >= om.GetComponent<Game_Sorting>().start)
            {
                om.transform.position = new Vector3(om.transform.position.x, om.transform.position.y + 45, 0);
            }
        }
    }
}
