Well there could be many signs. Yes nobody knows if vampire are real. Here are some signs: Pale skin, unusual eye color,goth clothing, great urge for meat, allergic to garlic.
These are SOME signs! If you want more you could Google 'Characteristics of a Vampire".
you cant they must tell you they hide their apperence (but how would you react if someone said the were a vampire to you. Would you believe them? This is why their secret must remain a secret)
If you drink blood, you are not necessarily a vampire. You may get sick from any contaminants that are in the blood, though. Most people require other vampiric signs, like not being able to go out in the sunlight, before they will call someone a vampire.
A vampire has to bite someone to make them a vampire. Then the vampire must feed the victim some of his own blood.
According to the books, if someone is bit, a vampire can suck back out the venom, but it's highly difficult to do.
There is -The Vampire Diaries -Vampire Academy Just google it.
Yes because the curse goes into you.
In order to turn someone a vampire must effect saliva transfer. As a psychic vampire has no need to do this the effect of his psychic-feeding would not result in the creation of another vampire. If however a psychic vampire were to resort to the usual means of feeding then yes, he could turn a victim into a vampire.

There is no such thing as a vampire possessing a human. A vampire can make a human into somewhat of a "slave", but they can't possess them.
When a vampire shows signs of pocession it will act strange like being silent or swallowing to show they want the persons blood or flesh. They will try to keep their pocession in infornt of people. Vampires will attack quickly and you do not have time to think about what is happening.
