Answer 1

You can specify user number = 6 in the get_categories function, for example

$talentChildren = get_categories(array('child_of' => get_category_by_slug('news')->term_id,'number' => 6,'hide_empty' => 0));
foreach($talentChildren as $talent):
    echo "<pre>";
    print_r($talent);
    echo "</pre>";
endforeach;
