I think this could be simplified. In your hierarchy you can make an empty button manager and make all of your buttons children of it. Then just use GameObject.SetActive(true) to have them appear again. This would work well if you wanted to work with all the buttons at once.

However, if you're looking at making different buttons appear/disappear at different times, you should make an empty __Manager and set each button as a GameObject in a script to manage them.

 // Your buttons
 public GameObject button1;
 public GameObject button2;
 public GameObject button3;
 
 // function to enable 
 public void enableButton(onButton){
     onButton.SetActive(true);
 }
 
 // function to disable
 public void disableButton(offButton){
     offButton.SetAdtive(false);
 }

You can add the public functions to an on/off button.

What you could do, is put all your buttons under one gameObject you wont hide, just a simple transform, and child all your buttons to it - since its a UI, use a "Panel", and turn off the Image component of that panel so it acts like just a parent or "holder"... Then in your script, you can find that panel object instead, and loop through each of the children.

 for (int i = 0; i < GameObject.Find("PanelWithButtons").transform.childCount; i++){
 GameObject.Find("PanelWithButtons").transform.getChild(i).gameObject.SetActive(true);
 }

General idea, untested code.

transform doesn't contain definition of getChild

Well the name "PanelWithButtons", is whatever name you gave the panel gameobject in the hierarchy, and it could also be GetChild, ins$$anonymous$$d of getChild as well.

You can put the same tag names to the buttons and you just do this code GameObject[] buttons = GameObject.FindGameObjectsWithTag("Buttons");
foreach(GameObject button in buttons){
button.SetActive(False);
}
