You've told us what the base is made of but omitted to mention what the figures are made of. (My guess is either bronze or spelter).
If they're original works by Emile Bruchon (who was sculpting, in France, at the end of the 19th century and in the early years of the 20th century) they might be worth a few hundred pounds each. (However, figures which are allegedly by Bruchon seem to be attracting no bids on eBay at the moment, despite having starting figures of under one hundred pounds each).
It would be worth taking them to a decent auctioneer for a (free) valuation. (Most people seem to think that you have to queue for hours at the Antiques Roadshow in order to get antiques valued free of charge. I've never had a problem with getting such a valuation, with no queueing at all, by simply walking into an auctioneer's premises, including both Sotheby's and Bonhams - where my items were valued by one of the Antiques Roadshow presenters anyway!).
