Hi Linds!
Honestly I've never tried feeding figs and dates to any Torts I used to work with. We would get a lot of veggie donations from the local produce stores and neither of the above mentioned fruits were included in those drop offs.
FWIW, when I was heavily into iguanas, dried figs were part of the salad mixture I would feed to them. My guys loved them! Mind you, they loved anything sweet! If I remember correctly, regular figs have a 6:1 calcium to phosperous ratio while dried figs have a 12:1 ratio. Please don't ask me why the drying process changes that ratio, I have no idea!
I'm hoping some of the more experienced Tort people on this forum can give you a definative answer to your question, but I would certainly try small amounts of figs with your Red Foot.
Cheers!
