Brebabob--That's an awful lot of foliage to be supported by such a small root system, but it's possible your plants will pull through with some extra care right now in the form of shade and high humidity. You might also consider snipping off some of the leaves to get a better balance between foliage and roots--the reason the plants are drooping is because they're not able to take up water through the roots fast enough to replace what is being lost through the leaves. Rigging up a "tent" from a plastic bag will raise the humidity, but use some sticks inside to prop up the plastic and hold it away from your leaves. Even if all the leaves wilt and die, don't give up hope, because there's a very good chance that new leaves will soon appear.
Regarding rooting hormone, I have not tried it on fig cuttings because others on the forum have said it's unnecessary and may even be detrimental. In my limited experience, fig cuttings tend to root quite readily without it--particularly on suckers with a few roots already started. As far as I know, root hormone doesn't speed up the rate at which existing roots develop, and you already have roots--you just need more time for them to develop further.
