All belong to
Platycheirus. The upper male is
P. granditarsus, and the middle female seems to be the same species. The lowermost female is difficult, as the yellow abdominal markings are hardly visible. There are several species with such dark legs, so I do not dare a guess.
It is recommended to post the pictures of only one fly per thread. And the more pictures from different angles we have, the easier is the identification ;).
