-Is it safe? Can I trust her to be who she says she is?

Generally speaking, I'd say no. You've never met in person, and have never Skyped or video chatted, so you have no idea if pictures match up to the person you're talking too. Why don't you try asking her to Skype or Google chat with you (Google+ has a free video chat feature, and it's much like Facebook). I'm an advocate for online safety, so being able to speak to her over webcam would pretty much confirm OR deny who she is.

-Is this sort of relationship healthy?Is it socially exeptable?

This relationship could be healthy. Who cares if it's socially acceptable or not. It's what YOU both want. Nobody should have a say or influence upon your decisions on whom you date. Since you mentioned her parents won't let her have a boyfriend, this could pose a problem, so I suggest if you want to keep this relationship, you have it remain a secret in terms of her parents. But, you communicate well, and speak often. I'd try speaking more often on the phone. She could explain that you're a friend from school, and you are both in the same class and talk about homework and such on the phone to her parents if they get suspicious. As long as you both make an effort, this relationship can be both healthy AND socially acceptable.

-I want to meet her and she the same with me. If we have the chance it would be at the mall,bringing one of our friends with us. Is this a smart choice of action?

This is a smart action only because you've decided to include a friend. If you don't get a chance to speak over video chat, and you're still skeptical on trusting her on she says she is, bringing a friend along is very wise. Usually, if someone is contemplating meeting someone they've met online, I was advise to bring a friend, preferably a male friend (whether it be male or female). That way, if your girlfriend turns out to be a 40 year old man, you won't be alone and you have better chances of getting out of the situation. Also, meeting in a crowded place like the mall is also a smart idea. Little to no chances of things going wrong, and if things are okay, plenty of things to do so chances are it won't get awkward for the first meeting.

Best of luck!
