top down game,enemies align next to each other

Hello,i am making a top down view game.

My enemies are spawning from different spawn points,seek for the player and they stop in an attack distance,where i play the attack animation.what i want to do is when they are next to my player i dont want them to push each other but align one next to each other like a circle.

my function is the following:

 function MoveAndRotate(targetPosition:Vector3) {
     var thisPosition:Vector3 = transform.position; 
 
     targetPosition = Vector3(targetPosition.x,thisPosition.y,targetPosition.z);
     
     transform.position = Vector3.SmoothDamp(thisPosition,targetPosition,velocity,smoothTime,maxSpeed);
 
     var toRotation:Quaternion;

 if (targetPosition - thisPosition != Vector3.zero) {
     toRotation = Quaternion.LookRotation(targetPosition - thisPosition);
     }
     transform.rotation = Quaternion.RotateTowards(transform.rotation,toRotation,maxRotationSpeed);
 
     var hit : RaycastHit;
     var forward  = transform.TransformDirection(Vector3.forward);
     
     if(Physics.Raycast(transform.position,forward,hit, 5))
     {
            if(hit.collider.tag == "Enemy")
            {
               transform.Rotate(Vector3.up * 30);
         }
     }

}
