Is there a possibility that none of them will exist?
I would do something like this

$possible = array('field_5b5b34f4ed085', 'field_5b5b34f4ed085', 'field_5b5b34f4ed085');
$field_key = false;
$field = false;
foreach ($possible as $key) {
  $field = get_field_object($key);
  if ($field) {
    $field_key = $key;
    break; // causes exit of loop when field is found
  }
}
// if field is not found
// $field_key and $field will both == false

// if field is found
// $field_key == the existing field key here
// $field == existing field object
