If you're one of the many Battlefield fans that have been looking forward to Battlefield 5 (and aren't the tittybabies who are upset that women are once again in the game), then you might be lucky enough to get into the Battlefield 5 closed alpha if you play the game on PC.
The closed alpha is mainly intended for PC players who speak English, and the closed alpha will also be invite-only, meaning that only those lucky players that actually get an invitation (likely Let's Players or well-known streamers) will be able to take part in the Battlefield 5 closed alpha gameplay.
The closed alpha will be intended to find out the various bugs that are in the game so far, along with the proper balancing of weapons, vehicles and other equipment. That will likely be coming not just with the alpha but also the beta of the game and pretty much every other sort of pre-release play period that will be coming before the game actually comes out later this year.
These requirements are only for the Battlefield 5 closed alpha so there's no guarantee they'll be the same ones for the full game.
Players will be able to play either Battlefield's classical Conquest mode, or the Grand Operation Fall of Norway. For all of your other questions for the game, you can follow this link to the information page.
