So nearly on the nail with the first 2. I think you've just missed the focus on #1 - the feathers look sharp, but the eye is a bit soft. Nice catchlight and good bokeh.
#2 is good for composition, but I think you've focused on the top branch.
Great light on both of those.
I'm afraid the others are simply out of focus.
(Don't feel offended - I don't really do birds, but that's partly because I know how hard it is to get it right - you've done well)
