The value of the ralationship field needs to be an array or all relationships, you can’t update them one at a time. Collect them in your loop and update them when the loop is completed.

$relatie = $latestpost[0]->ID;
$relatieID = get_field('week_palaver');
$day_posts = array();
foreach ($week as $weekday) {
  $PostID = wp_insert_post(array(
    'post_title'   => $latestpost[0]->post_title . ': ' . $weekday,
    'post_type'    => 'palaver',
    'query_var'    => true
  ));
  $day_posts[] = $PostID;
  wp_set_object_terms($PostID, $CatTermID, 'gebied');
}
update_field('field_5eea245f36217', $day_posts , $relatie);
