How to modify specific GameObjects in an array of GameObjects?

I want to “select” specific gameObjects in an array of gameObjects. In my case specifically, I want to modify all the gameObjects in the array, excluding the first gameObject (gameobject[0]).

Is there a way to somehow specify gameObject[1 - entire array of gameObjects after 1]? I suppose I would compare it to a range of integers that specify specific positions in the array (1 - gameObjectArray.Length) or something like that.

for (int i = 1; i < gameObjectArray.Length; ++i)
gameObjectArray // Do your modification here
If you want to exclude more elements or make it more general:
List elementsToExclude = new List(new int[] {0,4,7});

for (int i = 0; i < gameObjectArray.Length; ++i)
if (elementsToExclude.Contains(i))

gameObjectArray // Do your modifications here
