If one of my siblings and myself took the Ancestry DNA test would it tell us if we were siblings or half siblings?

I think you would need a paternity test for that.

DNA testing companies test for genetic markers commonly found in various human populations.

Not necessarily. It could tell you if your are related.

No, not 100%.
In theory, two siblings from the same two parents could have NO DNA in common.

If the DNA-company would compare both your DNA's, it would find that you share about 23 chromosomes if you are full siblings, and about 11 or 12 if you are halfsiblings.
DNA-ancestry-tests don't really find your ancestors. They find people with chromosomes (almost) identical to yours, like your 5th cousin twice removed, if those are in that company's database.
Some of those companies will even help you contact the relatives of yours that they find, provided that both parties involved give explicit permission for that

Yes it sure would.
