I've looked around online but I can't really find anything similar to these photos with helpful answers... I've seen the behind the scenes photos and they used a lot of lights, the studio I uses has 4 lights with soft boxes and a beauty dish so I need to create the lighting with those and reflectors etc.

Any help would be greatly appreciated.

I have a few ideas but it's good to get some opinions, I think.

I have seen some people using a soft box at ground level, one above the model and then some lighting on the background

These both look to be very simply lit with a light a little high and right of the subject according to the shadows. It is a little hard to tell with no give away catch lights.  But these are not complex and you should be able to recreate this look very easily.

There is fill, but you say that they had a complex lighting set behind this, It is pretty flatly lit so again, not as tough as recreating a specific shadow detail. I don't see background, hair, or edge lights. Very natural looking.

2 softbox or strip lights high and to the sides.  It's pretty flat lighting.  Look at the shadow under the chin of the first one and the shadow by the left arm to see the angles used by each light.  I would say the main to the left of the camera about 45 degrees with the edge of the light hitting right below her waist. The fill is lower on the right at a sharper angle.
For the second image it looks like two lights about 45 degrees from the camera center with equal power.
when trying to figure out lighting, always look for shadow angles in relationship to highlights.  The direction of the shadow will tell you the angle of the light making it and the highlight will help decide the where the center of the light is pointing.  Looking at the edge will give you an idea of the type of light modifier used once you get the hang of knowing how fast fall off happens with different sources.  Point lights fall off faster than large soft boxes and leave a harder shadow line.

Thank you both
