@AnisNajma

 public Image[] trolley;
         int healthy=0;
         int unhealthy = 0;
         private void Start()
         {
             for(int i=0;i<trolley.Length;i++)
             {
             if(trolley[i].tag == "healthy") // can also use if(trolley[i].CompareTag("healthy"))
             {
                 healthy += 1;
             }
             else if(trolley[i].tag == "unhealthy")
             {
                 unhealthy += 1;
             }
         }
 
         if(healthy == trolley.Length)
         {
             //Display Healthy Person
             Debug.Log("Healthy");
         }
         else if(unhealthy>=1)
         {
             //Display sick Person
             Debug.Log("Unhealthy");
         }
     }
