Like wishgranter said it looks exactly like what you would expect to see if the subject had moved between captures.
Assuming the 6 fixed cameras fired approximately simultaneously each time then you should not see these artifacts if you try working with just a single set of 6 images, only when you try combining more than one set.
Perhaps even 2 or 3 sequential sets of 6 images would be close enough together in time that any movement was small enough to not cause this, but it seems that over the 9 sets there was 'significant' movement.
Regarding focus, perhaps try to keep a constant distance and set focus manually. This would enable you to fire off your 9 sets of images more quickly too, plus photoscan prefers when sets of images have identical camera parameters (see in tools -> camera calibration) - changing focus changes the internal parameters such as focal length and distortion slightly each time.
