Health bar rotation on camera

Hello, I need help simplifying a script. I have a script that rotates the Health bar on the camera. Since I have a choice between two tanks at the beginning of the game (as a player) and each tank has a choice between Third personCam and sniperCam, I wrote it like this. The problem is that it doesn't work, or rather it works but badly. How could it be simplified and more importantly made functional? Thanks for the help

 public class Billboard : MonoBehaviour
 {
     public Camera camera1main; 
     public Camera camera2main;
     public Camera camera1snipe;
     public Camera camera2snipe;
 
     public Transform cam1main;
     public Transform cam2main;
     public Transform cam1snipe;
     public Transform cam2snipe;
 
     void LateUpdate()
     {
         //main camera
         if (camera1main.enabled == true)
         {
             transform.LookAt(transform.position + cam1main.forward);
         }
 
         else if (camera2main.enabled == true)
         {
             transform.LookAt(transform.position + cam2main.forward);
         }
 
         //sniper camera
         if (camera1snipe.enabled == true)
         {
             transform.LookAt(transform.position + cam1snipe.forward);
         }
