Answer 1

You can't use ORDER BY in IN clause subquery, and it doesn't make sense in the first place. So remove/comment it out:
select  employee_id,
        last_name,
        salary,
        job_id,
        (months_between(sysdate,hire_date)/12)
  from  employees
  where department_id in (10,20)
    and (months_between(sysdate,hire_date)/12>=6)
    and (months_between(sysdate,hire_date)/12<=10)
    and employee_id in (
                        select  manager_id
                          from  employees
                          where commission_pct is not null
    and job_id not in (
                       select  job
                         from  employees
                         where commission_pct>200
    and (months_between(sysdate,hire_date)/12>=7)
    and salary<2500
    and to_char(hire_date,'mon') not in('sep','nov')
    and employee_id in (
                        select  manager_id
                          from  employees
                          where manager_id not like '%9%'
                             or manager_id not like '%0%'
--                          order by department_id
