is my plant dying?

my grandpa who lived in bulgaria recently died, and he had been taking care of my dead grandmother’s plants. im not sure what they are, but i live in Savannah, Georgia. we brought these plants home with us since nobody would be able to take care of them in Bulgaria, but none of us have any idea how to take care of them, and we’re worried that this one might not survive. we arrived back 3 days ago, and it has looked like this ever since.
