What astronomical constellations are these? Help me, find them, now! !

B, unable to judge;

C, Ursa major, but there seems to be a lot of deviation in the position of Beidou 7.

D, I can't judge, there are too few stars.

E, it seems that no one does. Keep it.

F, Southern Pisces and Pisces should be the brightest, but you can't see them in the picture.

If we can accurately draw the positions of the stars in those constellations, we may be able to identify them, but we must first know whether the stars in several constellations are drawn together, and if so, it will be very difficult.
