Although it's never explicitly stated in the books or movies, the most likely answer is no.
There are way way way too many to name I'm a huge expert on Harry potter but you should google it
No, he does not. Hermione is very studious and is forever learning new spells , often she teaches Harry new ones.

Yes. So are the magic spells, the potions, many of the places mentioned (such as Hogwarts), most of the characters in the stories, and many of the creatures mentioned (such as dragons, dementors, etc.). In the real world, there is no magic of the type that appears in fantasy stories, such as Harry Potter.
Wikipedia has a list of many of the spells; search for "Harry Potter Spells". Several fansites also list the known spells; for example, the Harry Potter Lexicon (hp-lexicon.org). Please note that none of the spells work in real life; they are part of a fantasy story. Also, not all details about each of the spells are known; the sites mentioned, and others, only list details that appear in the books, for example, the exact words to say, if it has been mentioned in the books.
The book sold 11 million copies on the first day released in UK and US. Being a big Harry Potter fan myself, I was appalled when I first learned this. Go Harry Potter! Keep going strong! :)
Harry Potter had no brothers or sisters; he was an only child.
