My initial reaction is that #6 and #7 don't fit you as well as they could. I don't think the proportions of them are flattering on you, however maybe they are better with dresses?
My BR denim jacket bleeds colour as well, which is really disappointing. I haven't done anything yet to try to fix this, but I do intend to. Instead I just make sure I'm wearing it with dark clothes underneath.
And I like the blush Zara jacket, a lot.
Hard to tell the wear issues from photos.
I like your plan though... grouping then replacing the "worst" in each group is very smart.
