Can an Instance Array Recognize Separately Named Instances?

I have a script that makes an array of instances, but I need it to find separate instances. I doubt that they will ever become gameObjects. However, I have a separate question on that if you have a script that spawns gameObjects. Please respond if you do!

Raycasting may suggest a solution, and this question is really planning for the future. However, if you have an answer, please don't wait to post it. I am consistently working on this, and have spent half of my development time on this separate-instance-destroying issue.

Just a recap, I need it to recognize separate instances, perhaps by name, preferably totally separate. I would also love it if one could translate this into Java Script.

Here's the script:

     DeadReplace must contain a collider and a rigidbody, or it'll fall through the terrain. :-)

                 dead.rigidbody.maxAngularVelocity = 1;
                 dead.rigidbody.AddExplosionForce(BlastForce, transform.position, BlastRange*5, 0.0f);
             } else {
                 // tree is out of range - keep it
                 instances.Add(tree);

             Explode();

Any help is appreciated, provided that you actually know or have thought about it before posting. If you need more information, please comment.
