Best regards

The species on the first, 4th and 6th picture seem to be from the genus Rhinolophus (fam. Rhinilophidae, The Idividuals in the other pictures, in the larger groups must belong to the family of Vespertilionidae. But I cant determine them any further, I am no expert at all.

Dear Colleague,

when you ask for assistance, please be correct and provide at least locality information on your specimens.

Dear  Shahrukh: 

It is possible that may be Rhinolophus ferrumequinum by the way it has to cover only partially with the wings exposing the nose, but the lancet and the sella are poorly appreciated and can not be guaranteed at all with these pictures.

More opinions can be important.

Best regards.

Agree completely with answer 1
