    SELECT *
FROM
(
    SELECT *
    FROM
    (
       SELECT * FROM Table1 
       UNION ALL 
       SELECT * FROM Table2
       UNION ALL
       SELECT * FROM Table3 
       UNION ALL
    ) sub
    ORDER BY ID DESC
    LIMIT 3
) t 
ORDER BY Id ASC
LIMIT 1

    The second 2/3::

    SELECT *
FROM
(
    SELECT *
    FROM
    (
       SELECT * FROM Table1 
       UNION ALL 
       SELECT * FROM Table2
       UNION ALL
       SELECT * FROM Table3 
       UNION ALL
    ) sub
    ORDER BY ID DESC
    LIMIT 3
) t 
ORDER BY Id ASC
LIMIT 2, 1

    The last 1/3 record:

    SELECT *
FROM

    SELECT *
    FROM
    (
       SELECT * FROM Table1 
       UNION ALL 
       SELECT * FROM Table2
       UNION ALL
