eli5 Does gravity act the same for large objects as it does for small objects. So if I were to shrink planet Earth and the moon to say half the size and the distance between them too then would they continue orbiting. Would this also apply if they somehow became much larger?

Mass and thus density are extremely important when it comes to gravity. You should explain your question better: does the mass shrink/increase with the volume, or not? It really makes all the difference
