The more important thing is toe and they are very well done. A little less in the rear to avoid the infamous inner edge wear a little more in front to keep down the tramlining and weeble-wobble on top of crown.
When I DIY my alignment I aim for 0.15° toe all the way around. 0.15*60=9' or almost exactly what you have. FYI; atan (1/16 / 24)= 8.95' or 0.149° so I use a 1/16 " spacer on the front of string tight around the wheels. I adjust the toe until the string is as straight as possible. I actually usually pad the 1/16 up to 3/32 to make it easier to do visually and that matches almost perfectly the high end of BMW spec.
It's worked well for me: no abnormal tire wear and I can set toe after any suspension change that matters without making appointment or the expense of the pro shop.
Front camber is factory pinned and only has a comically small amount of adjustment if you pull the pin.
The front camber changes by a LOT every time you steer so as long as the pinned value doesn't appear to be modified by a crash no need to worry.
The rear camber of 2° is within spec, mine is over that but I have worn ball joints soon to be replaced. You are over spec but with the toe set properly I doubt you will get any strange wear as long as the ball joints are all tight.
They make camber bolts for the front end, I wonder if somebody makes similar for the rear for e53, that you can swap for the eccentric head bolts to get more adjustment than stock without having to resort to replacement arms.
