How to all GameObjects in array or 2 objects collide with 1 object at the same time

Question

I don't know how to put this and it's the middle of the night here and i'm tired lol

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class LeverMove : MonoBehaviour
 {
     public Animator LeverAnim;
     public DoorScript door;
 
     public GameObject[] Players;
     void Update()
     {
         Players = GameObject.FindGameObjectsWithTag("Player");
     }
 
     private void OnTriggerStay2D(Collider2D collision)
     {
         if (Players[0 & 1] && Input.GetKey(KeyCode.Q))
         {
             LeverAnim.SetTrigger("LeverMoves");
             door.DoorOpen();
         }
         else
         {
             return;
         }
          
     }
 }

so this is my code and what I wanna achieve is I want the players to all be (or only 2 of them) be at a single trigger at the same time and whilst that's happening the player should be able to press a key for the command to execute, anyone know how I can achieve this, Thanks!

You should use OnTriggerEnter and OnTriggerExit, to keep game objects in a list, then compare the lists for similar items. For example:

 public GameObject[] Players;
 public List<GameObject> PlayersInTrigger;
 
 void OnTriggerEnter2D(Collider2D collision)
 {
      PlayersInTrigger.Add(collision.gameObject);
 }
 
 void OnTriggerExit2D(Collider2D collision)
 {
      PlayersInTrigger.Remove(collision.gameObject);
 }
 
 void Update()
 {
      foreach (var player in Players)
      {
           if (!PlayersInTrigger.Contains(player))
               return;
      }
 
      // If code reaches this spot, all the players are in the trigger
 }

If your trigger is more simple, like a sphere or box collider, use Physics2D.OverlapCircleAll, (which returns all colliders within a circle trigger of said radius), and check if each player is in that array of colliders. If so, they are in the trigger. Hope that helps @yousifalsewaidi
