How do I adjust Myfunction on UnityEvent Inspector?

Can my functions that will be shown in UnityEvent fall apart or adjust the order like screenshots?

Nope, sorry, it’s actually impossible. You could make a custom inspector, and maybe there you could tweak that, but it would require modifying the button component which is impossible because it’s an internal class.
You will need to keep searching for the functions, and wait unity comes with a better solution in the feature.
