If you store your objects first in an array, you can use a foreach on that array of objects calculating distance using Vector3 distance and the closest objects would obviously be the neighbors. You could also just using something simple such as OnCollisionStay or in 2d it would be OnCollisionStay2D. https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionStay.html https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionStay2D.html
