Bummer about the ones you had to give away but you've got a nice collection going there! The one from your first photo with the dark leaves is a rubber plant for sure. That was the first plant I ever owned and it didn't last long.
Unfortunately, most of the outdoor plants for you are stuck as houseplants for me. Maybe that's why I live in Australia in so many of my dreams...
I couldn't let it go and wound up IDing the one with the gourd-shaped leaves as a Plumeria pudica!
