    First of all, it seems like answer to 3. will be 8*number of rows, but…

    answer 1:

    SELECT SUM (8-(h1+h2+h3+h4+h5+h6+h7+h8)) FROM table WHERE id=YourID

    answer 2:

    SELECT SUM (h1+h2+h3+h4+h5+h6+h7+h8) FROM table WHERE id=YourID

    answer 3:

    SELECT SUM (8 as x) FROM table WHERE id=YourID

    and answer 4:

    figure it out yourself, you should have enough to start your journey now 🙂
