Get other users data custom value how can I get all (custom) data from other users ?

With my admin account, I want to show them in a page. 

For example :


  
  user 1 : 
  
  
  name
  age
  custValue
  
  
  custValue1 / 2  / 3
  
  
  


I want to get custValue and the other data (custValue is the most important)

Example of values that I want to show :
Drupal 8 :

$user = \Drupal\user\Entity\User::load($uid);
$value = $user-&gt;field_name-&gt;value;


For multiple values, use

$value = $user-&gt;get('field_name')-&gt;getValue();
