Yes, they do, if the owner happens to be at his store at 3:00 AM to demand that they leave. If not, other ordinances are necessary to keep things peaceful.

Wouldn't a posting saying "No trespassing after 10:00PM" do just as well? The owners could post at notify the police. I don't know - I'm just asking.

Regardless, if they are not being peaceful then their surely are other laws that can be used. If they are being peaceful then there's not problem anyway.

I'm not positive about that one. Generally, though, a sign isn't as strong as a specific order when things go to court.

If the kids were being peaceful, which is rarely when large groups of them are together really late at night, then we wouldn't give them too much heat. We'd just keep an eye on them and make sure it stayed quiet. Of course, different officers had different levels of tolerance for this.
