You'll need to use table aliases.

SELECT
        orders.id,
        orders.order_number,
        clients.first_name,
        clients.last_name,
        creator.name AS creator_user_name
        editor.name AS editor_user_name
FROM orders

INNER JOIN clients ON
        orders.client_id = clients.id

INNER JOIN users creator ON
        orders.created_by = creator.id

INNER JOIN users editor ON
        orders.edited_by = editor.id
