First the easy one. The small blue, black and white guy with the little pocket handkerchief showing on his wing is a male Black-throated Blue Warbler.
Next, the thrush. With a reddish tinge to the back half of the bird and a greyer tinge to the head I'll say that bird is a Hermit Thrush.
And now for the hard one. Obviously it is one of the two smaller accipiters and I'm much more comfortable identifying them in the air. The Cooper's Hawk is larger, has slower wingbeats, has a larger looking head and the end of the tail seems rounded. Unfortunately, I can't see any of that in the picture.
There seems to be a clean break between the dark cap and the paler nape which would lean me toward Cooper's Hawk (in Sharp-shinned the dark head tends to fade into the neck resulting in a more "hooded" rather than "capped" appearance). And the fluffiness around the base of the tail I have seen before in Cooper's and never to the same degree in Sharp-shinned (which doesn't mean that it doesn't happen... just that I've never seen it). So, I will rather tentatively say Cooper's Hawk.
