Absolutely clear as mud :P

I think this might be what you're after

SELECT
        docnum,
        alias1,
        alias2,
        subclass_alias
FROM
        docmaster
WHERE
        subclass_alias = 'Inquiry'
    AND alias1        IN
        (
                SELECT
                        alias1
                FROM
                        docmaster
                WHERE
                        subclass_alias = 'Reply'
                    AND
                        (
                                alias2 = 'Pending'
                             OR alias2 = 'Redraft'
                        )
        )
