I am taking herbal supplements fish oil, estrogen, multiple vitamin, hyaluronic acid, pumpkin seed oil. Are these safe to take with each other?

Not really, but why? Who knows? They may not even be safe by themselves, as you never really know what's in them to begin with. Why are you taking them in the first place. What are you attempting to fix, and how are you going to tell if any of them help -- what criteria are you going to use. They will commonly interact adversely with other supplements and also with prescription meds. Avoid at all costs.
