If they are just dried figs a tiny piece would be okay but if they have a lot of sugar do not give them to your rats! Check the package for how much sugar is in them. Also figs are notorious for helping move your bowels so if you give them too much fig they might get diarrhea.
some people give very small amounts of dried fruit, but only small amounts because they contain so much sugar
