Having a baby I need names with good nick names what do u think of these?

They're all pretty good. I love the name Sebastian and considered it for my son, but decided against it since there isn't a good nickname for it. Bastian doesn't sound "right"...almost sounds vulgar. I'd probably avoid Elizabeth since it's so common (even though it's the most versatile) and go for one of it's variations: Lilibet. Of course, you could call her that if you named her Elizabeth.
