Stone carving Figures

Stone carving Figures, 5” tall
Really not sure about these at all - what rock are they? ( alabaster? ), and where are they from ?
At first I thought Latin or South American. Google images seems to point towards Native American Indian. And I did find one Native American Indian example with feet on the base like the woman here - I like that!
Any ideas appreciated. Not signed, unfortunately.
Thank you!

I've not come across carvings like these before, but from their outfits I think South American or Southern USA is likely. The first one looks more Inca style than the second one

They were bought together. Stone looks the same to my untrained eyes. I thought Inca or similar to start with but can’t find anything with quite same headgear or pose.
