You could put something like this on all your boxes. Note it assumes that the boxes are tagged “Red” and “Green” for red and green boxes:

#pragma strict

function OnCollisionEnter(col : Collision) {
	if (col.collider.name != "Ball")
		return;
	
	var tag = gameObject.tag;
	
	var hit : RaycastHit;
    // Check the boxes above
	while(Physics.Raycast(transform.position, Vector3.up, hit)) {
		if (hit.collider.tag != tag)
			break;
		hit.collider.enabled = false;
		Destroy(hit.collider.gameObject);
	}
	// Check the boxes below
	while(Physics.Raycast(transform.position, Vector3.down, hit)) {
		if (hit.collider.tag != tag)
			break;
		hit.collider.enabled = false;
		Destroy(hit.collider.gameObject);
	}
	Destroy(gameObject);
}

doing anything with raycast here is overkill, this should be handled in the datamodel. Store references to your boxes in a 2D array for example (as you have rows of boxes). Or create a linked list implementation in which each box has a reference to the top and bottom box.
