Ambient versus klonopin (clonazepam) can they be taken together?

Yes, reluctantly: Clonazepam is used for anxiety reduction, it has little sleep inducing effect. Ambien (zolpidem) is for sleep induction, it has little anti-anxiety effect. However, together you could get more than an additive effect, which could be dangerous. Talk to your doctor about the uses for each, then consider trying the one that fits your problem the better. There are other ways to solve these problems as well!
