Ah. Sorry. I should have posted all the number of moves from the beginning.
No, this isn't one of my games. It's a game from an e-book I downloaded a long time ago. Can't remember where. All I have is the fuseki.
4: Bad. This invites black C3 or D4, at which point white's stone has become weak and black has made territory - so white's move has forced white to get strong. This kind of underneath shoulder hit is usually bad, for exactly this reason.
5: Bad. If black wants to go this way, D4 is a harsh way to punish white for making a bad shape. C3 is an easy way to take territory.
6: Bad. Black C3 now leaves the D3 stone completely wasted, and white without a base. C3 seems essential for white to make good shape, and leaves black with bad aji if white plays C6.
7: Bad. C3 is a vital poitn for both groups in that corner, and sente for both against the other. It is a vital fuseki point.
8: Bad, because black C3 makes his group strong and makes white's group weak. Although it is an extension from the upper left, it seems to not address white's main problems.
9: Bad. This underneath shoulder hit invites white C9, black D8 and white E8 to seal black in strongly (there are other variations, but submissive). Because the shape is too bad for black, he should rarely want to play this kind of move, just like white D3 was wrong earlier. Black C3 still seems like the vital shape point - it is still important for the safety of two competing groups.
10: Bad. This ignores C3 and C9, both of which are very big shape points. I think C3 is the more important, because then black must crawl and the D9 stone is light.
11: (Assuming this is the intent of the marked stone), bad, because black has two big problems in the bottom left. I think he should solve them, probably with C3 to leave white in bad shape on the bottom.
This is a good example of a lower level opening where something important is overlooked which could give one player an early massive advantage. There is some great stuff to learn from it, if you can understand why both players' moves were bad, but it is a funny opening problem.
I would rather let the mistake be D9, because its easy to treat light. I'm also wondering oso, is this one of your games? 
is unusual but i might play that depends on my mood.
is ddk ish
is sdk ish
is tdk ish
is qdk ish edit: maybe i streach this a liitle but..still it is a bad move.
) than your suggestions 
. I don't see the danger you are talking about on the top though, as far as I can see White should easily get sente to fix it.
