Chinese ivory figures

Hi, I have some chinese ivory, one jade. I cannot understand the signatures. Any idea on their age? The signature?
Thanks Neta

The green figure is Malachite not Jade..it is a copper ore and that is lovely.
My son will look at the other figures later as he is very good on chinese antiques as he works in an antique auction room an dit is becoming his speciality

Be aware that you are not allowed to sell ivory items on eBid.

No expert on dating, etc of ivory pieces, but most look more modern to me, except the woman figure. Not sure about the feet though, they look kind of modern to me. I would not buy or sell pre-banned ivory online. I belong to a collector's society, and have access to live assessments by experts, presentations, etc.

I may pop a few pics in here for comment.
