No, I don't think realized figured bass parts are available for free online of any of these works.
Actually, figured bass or basso continuo notation is not that hard to read. In the simplest form, one just needs to play the bass as written in the left hand and add top 3 voices for the right hand in the closed position. The figures or numbers above the bass indicate which intervals should sound. The third is almost always implied except in such cases as 5/4 which is a suspension. Then the 4 becomes 3. + or # indicates a raised interval whereas b or - is for the lowered interval. If the bass note is without a number, then it is a root position triad. 6- means a 1st inversion chord, 6/4 - 2nd inversion chord and so forth.
