The ladies are described from left to right. Juliana Cavendish Philips' article in thepeerage is here. Her married name became Duncan-Haldane. Emily Mary, née Grimston, Countess Craven's article in thepeerage is here. Lady Louisa Grace Fortescue, née Butler's, article in thepeerage is here.

The prints were found on eBay as Queen Victoria Court Beaut(ies). Viscountess Duncan's portrait is also at the National Portrait Gallery, London (NPG); they state it is by William Henry Egleton, after Frank Stone and that it was published in 1841. Countess Emily Craven's portrait, by William Holl Jr., and by Francis Holl, after John Hayter published 1840, is also there as is Lady Louisa Grace Fortescue's portrait, by Edward Francis Finden, printed by McQueen (Macqueen), published by T.G. March, after Andrew Robertson in 1842. However, I could not find Mrs. Montague Fox-Maule's portrait at NPG.
