2 different types of shorebirds. Manzanilla, Jalisco, Mexico
Semi-Palmated Plover the 2 to the upper right. Wish I could see more of the face on the one below it
that one is most likely a Greater yellowlegs given the bill length
Fairly sure it's a Least Sandpiper in front on the first pic, but not totally certain.
Greater Yellowlegs in the second pic.
