Forex is the foreign stock exchange. If you’ve downloaded the official software from forex.com, live support personnel can help you, but it isn’t something you learn overnight. You should try to find some good books at your library or on amazon that explain forex, and how to get started.

2- From software When I can buy and when I can sell? From where I can get information that this is for sale and How much I am getting/

You can use the official forex software. Instead of selecting "Practice", when you login, you would select "Live", and you would be trading on the real market.

3- How can I sell? How can I buy?

Again, you should get a book introducing you to forex. Buying and selling is as simple as clicking Buy or Sell, but if you don’t know what you’re buying, it’s pointless.

4- How I will get money or How and were I can deposit money?

I believe forex uses your bank account to withdrawl and deposit however much money you chose.
