In Drupal 7 I loaded the node/entity I want with node_load / entity_load and, if necessary, then I took a field with multiple deltas and take the value I wanted with a foreach loop.

In Drupal 8 how can I do the same in a hook?

For example, this loads my first value of a field:

$a_id = $adress->field_a->target_id;

In this case an entity reference field. But there are more target_ids.

So how to take them?

    $adress->field_a should be iterable..so foreach ($address->field_a as $item)? – Clive Jan 6 '16 at 16:59
  • Yes indeed, that's correct. I think I need a long time for d8! Tanks a lot! – maen Jan 6 '16 at 18:04

    @Clive you should add that as the answer :) You need the points! ;) – Berdir Jan 6 '16 at 18:33
  • @Berdir Shhh I'm trying to let someone else answer it so maybe they get the points...these things are heavy ;) – Clive Jan 7 '16 at 23:55

Entity reference fields have a method called referencedEntities().

Usage example:

$addresses = $entity->get('address');
foreach($addresses->referencedEntities() as $delta => $address) {
  // Do something with the $address entity
}

P.S. If you only want the field then as @Clive mentioned you can just iterate over $addresses.
