Hey dude, don't worry. The thing which you have explained is completely normal. Enjoy your vibrations.
1) No! you are invisible. But you will be able to see/hear other people in physical plane
2) I haven't tried it, but I have heard that many people does that, there are something like Astral temple, where many people meet in astral form.
Yes you can, but needs a hell lot of practice bro. By the time you achieve that, you might think lottery doesn't matter, you might get into full time spirituality. Ha ha.
In short, yes!
Yeah, It's normal. I used to experience this sometimes. You can stay calm and try to see your surrounding with closed eyes, it will avoid this weird experience and helps you exit your body.

Thanks for the awesome response, I will surely watch those movies over the weekend. I watched Insidious already, It's a great horror movie, but still many things that old lady says is misguiding. (except, "you no need to be scared, as you the one who is alive")
