To make it sure,
I'll stay alone at the first night, but at the second night my filipino friend will stay with me overnight. Will you charge me extra or not in such a case?
No you can bring anybody to your room. And if somebody comes in without you, they will call you first to make sure you know the person.
Problem with this answer?
no they will not but you can tell them your friend is coming the following day.

Yes you can bring anyone to your room but they must tag along with you otherwise your friend will not be allowed in.
