Somebody get me or somebody explaon how can i get it my self

The way it works is both people add each other on bnet, then wait 72 hours.

Then you send the guy 2000fg who is gifting you a copy of D2R, and then he will gift you the game on bnet.

The copy is a gifl with the game?
And if so, when i receive the gift i can load two diablos?

Bro you're asking technical questions if you're asking how to load multiple copies of D2R at the same time, you need to google that, the answer is there on the internet.

Regarding your first question, the gift IS the game.
