Using three different light sources, the key light which is placed 45 degrees to the side of the subject, the fill light which is opposite the camera often a reflector is used, and a back lighting. This lighting can be identified but the triangle shaped light under the eye, as shown in the second image.

Edge lighting

Edge lighting is when only one side of the face is in light and the other side has a shadow cast upon it.  It's one of the easiest lighting set ups as the main light only needs to be on one side of the subject while the camera if facing it. 

Butterfly lighting

Butterfly lighting is lighting that creates a shadow below the subjects nose that resembles a butterfly. This lighting is from a single light source placed higher than the subject but not directly above them. This lighting is often used to create softer lighting to make mostly females prettier.
