Auguste Moreau male and female figurine lamps

First you would have to determine what they are made of, bronze or spelter. as they have been painted it's likely they are spelter. Spelter is a zinc alloy that is often plated bronze, when thr bronze plating begings to wear off they were often painted.

Lamps of this type tend to date from the first quarter of the 20th century, and are not original Moreau pieces, but based on his work. Here's a link to comparable lamps at auction:
