Usually you would refer to your "full sister" rather than a "whole sister" (in my experience) and mention her before the half-brother and haf-sister. Also, I'd expect to hear which was dad's side and which was mom's.
I not only have a full sister, but also a half-brother and half-sister on my dad's side, and two step-brothers from my mom's second marriage. I have family around the world.
Use "family" in the uncountable sense.
