Answer 1

I added a subquery to get all your friends since I assumed that if you have these records

Friends
==================================
ID      TO       FROM     STATUS
==================================
1       1        2         1
2       3        1         1

and your member_id = 1, your friends are 2, 3. right?

SELECT  b.f_name,
        b.L_name,
        c.`text`
FROM
    (
        SELECT `to` friendID
        FROM    friends
        WHERE   `status` = 1 AND
                `from` = ?             -- change this to your ID
        UNION
        SELECT `from` friendID
        FROM    friends
        WHERE   `status` = 1 AND
                `to` = ?               -- change this to your ID
    ) a  INNER JOIN members b
            ON a.friendID = b.member_ID
        LEFT JOIN   posts c
            ON a.friendID = c.user_id
