Find them and recruit them. Some of them, hyave to require for you to do a certain quest, when others, all you have to do is talk to them and recruit them. Here are some of them:



Arcade Gannon-Location-In Freeside, in the Old Mormon Fort, where, the "Followers Of the Apocolapyse", stay.



Lily-Location-Jacobstown. You can find the location of Jacobstown, in the Old Mormon Fort in Freeside. Julia Farkas will give you the location, when you start the quest, "Nothin' but a Hound Dog".



Rex-Location-Freeside, in "The Kings". He is a dog, you can get from The King. You can find the King in Freeside.



Cass-Location-Mojave Outpost, in the Mojave Outpost Bar, sitting in a chair. You'll have to finish the quest, "Heartache by the Number", first, which you can start, by talking to Cass.



ED-E-Location-Primm, in the door which you can see, when you first enter Primm, on your right. I forgot what the door was called though.



Veronica-Location-188 Trading Outpost. Veronica is standing right outside, looking over a bridge. Talk to her and you have her.



Boone-Location-Novac-When doing the quest, "They Went That-A-Way" you will unlock the location of Novac. Boone is up in the Big Dinosaur's Mouth. You'll see the Big Dinosaur(Not Real), once you walk into Novac. Talk to him, and you'll start the quest, "One For My Baby". You have to find out, who enslaved Boone's Wife, Carla, to slavers. It's Jeannie May Crawford, who you can find at the front desk, in Novac. Boone will shoot her. Talk to Boone again to recruit him.



Raul-Location-Black Mountain, in the Prison Barracks, waiting to be saved. Walk up to him and recruit.
You have to find them and recruit them. You'll have to do a quest as well. Arcade Gannon and Veronica are the only ones I know that you don't have to do a quest for. They're both great.

Arcade Gannon is found at the Old Mormon Fort at Freeside. You need a certain speech level or the Confirmed Bachelor perk to recruit him. (If you help the Legion, he'll eventually leave you.)

Veronica is found at Trading Post 188, a ways SouthEast from Vegas. You just have to tell her that you'll take her out to see the open world. (If you kill enough Brotherhood members, she'll leave you.

Rex is a cyberdog, and he is found also in Freeside. He's obtained by doing a few quest for the leader of the Kings Gang, the King.

If you like to do some sniping i have the perfect companion for you. When you get to the town with the big dinosaur and the motel (forgot name sorry) east of the REPCON facility. There will be two snipers living in this town that used to work for the NCR but now protect the town. They switch guard shifts in the dinosaurs mouth when the sun goes down and when it comes up. Look for Boone, his wife was kidnapped and he asks you to find who is responsible for her disappearance. You can go around and ask all the town folk but do not waste your time. At night sneak into the motel lobby and behind the desk there will be a safe on the ground. It is a easy lock pick and there will be proof that the motel owner, a older lady, is the culprit. The quest will have you lead her in front of the dinosaur during Boone's shift and he will blow her brains out! Go talk to him and show the proof. After this you can talk to him and he will join you to seek vengeance against the Legion(the slavers who bought his wife). He is a valuable companion as a sniper because he gives you a spotter perk. Whenever you are looking through a scope you enemies will glow, even at night. Plus he does some major damage with his sniper.
To get companions to you need to find them and friend then.



The main companions:



Rex- cyborg dog belonging to the king in freedside

Arcade Gannon- scientist

Craig Boone- sniper in the dinosaur (could be companion only if you are friends with ncr) btw he is the best of all the companions

Lily Bowen- nightkin

Raul Tejada- ghoulHow do you get companions in fallout new Vegas?
