This is probably a composite of several shots with each individual shot separately.
The main light appears to be from slightly above and to the side causing a highlight on one side – due to the harshness of the transition from bright to shadow and the fall off to shadow towards the legs this is likely a gridded beauty dish or snoot. There is proabably a 2nd light from above and on the opposite side that is using a blue colour gel – you can get blue tint effects with white balance but this would tint everything and the main light is very clearly white still so colour gel is more likely.
Finally there may be a 3rd light or reflector softening the shadow on the side opposite the main light.
They appear to be trying to give the impression the light is coming from the table so have lit from different sides of each model to make the direction of the light source be the table.
