Drupal EntityQuery is the solution. For that, you can use the following code
$query = \Drupal::entityQuery('user');$query->condition('name', '%admin%','LIKE');

Find Entity using Drupal EntityQuery
Could try this too
$roleNeeded = 'Staff'$currentUserId = $currentUserId = \Drupal::currentUser()->id(); \\ or use Drupal\Core\Session\AccountProxyInterface; if using DI$loadUser = \Drupal::entityTypeManager()->getStorage('user')->load($currentUserId);$loadUser->set('roles',$roleNeeded );$loadUser->save();An easier way to get all the roles
Another way to get all the roles would be using the "user_roles()" function, that function even filter the anonymous users if we want to.
