Gold in blizzarad wow server can exchange to real cash?

I have a friend who actually bought gold from a website through his credit card. There are also some people who exchange gold for paypal credits or the likes. I myself would like to sell gold if there are interested buyers out there.

Yes u can buy gold for real money from numerous sites. I don't know why people would waste there money but you can. Some people are known as "gold farmers" on the game and have bots that auto play there characters to grind a certain set of creatures/mobs for money gold making and then sell there gold to a company which then offers gold for cash. Happens all the time on every server guaranteed.

No. Certainly no.
