Oops. Fuyu, not "fuji." Silly typo.
Try freezing the others after totally ripe. Then, run them under warm water to remove the skin with your hands. Slice and eat like a natural sorbet. Yum. Or, of course, bake with them or put them in a smoothie.
They will ripen if picked when green if they are left alone. But they will never be as nice as allowed to orange up on the tree.
