Though there is no sure way to tell, it probably does mean that. To be sure, try listening to the tone in his voice.
It means he wants to have sex with you.
It depends. If a girl says it she means her female friend. Sometimes when a guy says it he also means a female friend. However, he may also mean a girl he is having sexual relations with but is not in a relationship with. ex: Female: Look I need to go call my homegirl and see if she if she can watch little Troy. ex: Male: No baby don't even worry about her, she's just my homegirl. ex: Male: So what if we smashed last night, you and me we ain't nothing, you just my homegirl!
It means You are Just Friends. Unless YOu want it To mean more.

Just laugh and say No way this is my girl
She either likes you or just calls everyone babe.
Deb is a fish and she calls her "sister" Flo, which is really just her reflection.
Pass it on to your boyfriend
Okay so a girl you know, calls you a hero? That can be easily explained, when a girl calls you this name. It is just a way she is expressing herself, that she likes you. And not only that, but that she wants to be with you. Honestly it depends on the girl that called you a hero, but in general it is a way of flirting and emotion.
If he calls every girl "hun", it's just a habit. If it's just you, it's a term of affection and he likes you.
* There are two terms for 'sister.' One is an old slang term used up until the 1950's. Example: 'Listen sister, I had this taxi before you.' If a person has a friend of the opposite sex and they refer to them as 'sister' then yes, that means that person is endearing to them; thinks of them as a sister with no romance involved.
She could either be flirting or just giving you a nickname.
