They look like green cheek conures.
Quakers /Monk parakeets are twice as big as green cheeks, their nares are covered with feathers whereas green cheek nostrils are bare, quakers are much lighter lime green rather than dark forest green, have a soft gray cowl as opposed to the deep colored GC, Quakers have horn colored beaks rather than dark blackish beaks, Quakers do not have the reddish green belly, red tail, and white eye rings that green cheeks do, Quakers have pale gray legs while GC have dark colored legs, and Quakers are 18 times as loud but better imitators of himan speech with the capability of learning as many words as an African gray.
Other than that they look the same.
