Yes, those hairs (and the figure they were made for) will work in DAZ Studio - though the materials may need adjusting, especially if you render in Iray. To use them on G2F you can either try AutoFit, if you have the Victoria 4 clone shape, or you can not fit them and simply parent them to the head (adjust scale and position to get them more or less right, then apply a Smoothing Modifier and set G2F as the collision target to tidy up).
