I think I've got the ID correct on these, but can someone confirm? Talkin' bout the little ones on the right.
CLOSED: Wilson's Plover?
The one standing up with a breast band is a Semipalmated Plover; there's a second sat down facing left just below left of it. The two sat down furthest right are a Calidris sandpiper, possibly Least Sandpiper, but can't see them well enough to be sure. There's a third Calidris standing just left preening its belly, either a Dunlin or a Semipalmated Sandpiper. Big bird is a Long-billed Curlew.
