This is a three-step process. Since your didn't share the entire code/HTML, I'll just give you the steps that are needed:

  1. Make sure that ButtonApproveClick knows what specific button the user clicked on.
  2. Then find the Firebase key/id of the child node in that row (typically by storing the key/id in an id attribute of that row).
  3. Finally pass the key/id into the database call to update: firebase.database().ref().child('Users').child(keyOfUserThatWasClicked).update({ statuss: "valid" }). You don't need the once() listener here.

A simple example of how you might be rendering the users:

firebase.database().ref().child('Users').on('value', function(snapshot) {
  snapshot.forEach(function(userSnapshot) {
    var tr = document.createElement('tr');
    tr.id = userSnapshot.key;
    // TODO: populate the rest of the row and add it to the table
});

You might then get the ID of the row the user clicked on with:

function ButtonApproveClick(e){
    var button = e.target;
    var tr = e.parentElement.parentElement; // might need more or fewer to reach the right/TR element in the HTML
    var key = tr.id;
    firebase.database().ref().child('Users').child(key).update({ statuss: "valid" })
}
