Could you please be more specific.
Vacant means Empty, therefore, a sentence you could use is: "The parking-lot is completely vacant."

It could be used in any sentence as an adjective. That sentence could be, "I'm quite busty and I fear it would look matronly on me."
Somebody will have to improve on this answer. One similarity between a sentence and a sentence fragment could be a sentence's length. If somebody says, "Who did that?" you could answer, "I did," and that is a sentence... but in a different scenario, that may be considered a sentence fragment. Why? Because if that sentence was all by itself, "I did," would be nonsense. What did "I" do? "I did jump," could then complete it.
Your question is itself a sentence which uses the word "could".
I could give you a sentence easily. You could also write your own sentences if you tried.
