Just to add to what dearest Glinzek has said, here is the manuscript of Bachs Lute Suite in G minor: (BWV 995) (I dont think this is the one that Bach hiimself wrote but… oh well)

Also, Bach’s Cello Suite No. 5 in C Minor. The website says that his second wife wrote out this manuscript, but I dont know how accurate that is:

You will not find his facsimiles on the itnernet, unfortunately. They tend to be tightly held, and of course they are priceless — but not unattainable.

Not all of the manuscripts of Bach’s works have been found or are even in existence. Many of his earlier works remain lost, so there may not be facsimiles for the BWV’s that you have specified — I could find no references for them, but my search was not exhaustive.

You may have run into some of this before, but just in case you haven’ —

At the following site

you can find sources for these facsimeles:

Orgelbüchlein. BWV 599-644. Faksimile des Autographs. Herausgegeben von Heinz-Harald Löhlein [Deutsche Staatsbibl. Berlin, mus. ms. autogr. Bach P 283].
Documenta Musicologica, II/11. Kassel, 4/ 1999. Oblong, 20 x 17 cm, xxviii, 184 pp. 2-color collotype reproduction of the autograph manuscript. The most important and comprehensive chorale collection in the organ repertory. Codicologically the manuscript—a torso—tells us a lot about the developmental process of the collection and suggests that Bach had been compiling the Orgelbüchlein over several years. Although an anthology of 164 chorale arrangements was intended, only about one third that amount was actually copied. Nearly all of these originate from the Weimar period (1708-1717). Introduction in German, with index. Hardbound. $79 (more info… ) [item no.78]
