Will Oracle optimizer use multiple Hints in the same SELECT?

SELECT /*+ INDEX(i dcf_vol_prospect_ids_idx)*/
       /*+ LEADING(i vol) */
       /*+ ALL_ROWS */
       i.id_number,
       ...
  FROM i_table i
  JOIN vol_table vol on vol.id_number = i.id_number
  JOIN to_a_bunch_of_other_tables...
 WHERE i.solicitor_id = '123'
   AND vol.solicitable_ind = 1;

SELECT /*+ LEADING(e2 e1) USE_NL(e1) INDEX(e1 emp_emp_id_pk)
           USE_MERGE(j) FULL(j) */
    e1.first_name, e1.last_name, j.job_id, sum(e2.salary) total_sal
FROM employees e1, employees e2, job_history j
WHERE e1.employee_id = e2.manager_id
  AND e1.employee_id = j.employee_id
  AND e1.hire_date = j.start_date
GROUP BY e1.first_name, e1.last_name, j.job_id   ORDER BY total_sal;
