To answer your original question, yes they are technically the same.
Ben came to the island with the Dharma Initiative as a kid, and the DI was often attacked (or so they say) by "hostiles" or "natives" of the island. When Ben grew up he joined sides with the hostiles and helped kill off the DI people.
Ben and his new friends recruited some off island people to join their little community and they collectively became known as "the others."
We still don't know who made up the hostiles/natives before Ben came along and recruited people. We know that they were led by Richard Alpert, but we know very little else about them. They could be people from the Black Rock, they could have lived there for thousands of years, or they could be time-travelling space monkeys. Except for Richard of course. No, Richard too.
And then of course you have the Losties, and the Tailies (some of which joined The Others and some of which are now part of the Losties), the Freighties (or whatever you want to call them), and Jacob, and the dead people that keep showing up...oh and then the people from Danielle's group, who knows what happened to them. And then there's Adam and Eve, and Desmond who shipwrecked onto the island as well...
My god there are a lot of people on this island.
