How to get 2 CircleCollider2d components with the same name in an object in C#?.

I use

CircleCollider2D cir;

     void Start ()
        {
                          cir = GameObject.FindWithTag("Plant").GetComponent<CircleCollider2D>();
    
                          cir.istrigger = true;
    
    }

but it just affect to the 1st CircleCollider2D only.
and I dont know how to use Getcomponents (with s)

If i understood you correctly you want to get 2 objects , with a mouse click, here’s my code , basically i find Gameobject with the name 1 , and then , after i press mouse button i’m getting component circlecollider2d and access to it’s istrigger attribute and set it to true , and right after i did that, script is searching for another one circlecollider2d with the name 1 :

void Start () {
        obj = GameObject.Find("1");
	}
	
	
	void Update () {
       if( Input.GetMouseButton(1)){
            obj.GetComponent<CircleCollider2D>().isTrigger = true;
            obj = GameObject.Find("1");
        }
	}
}
