Assassin's Creed and Assassin's Creed 2 were both developed by Ubisoft Montreal, and published by Ubisoft.
Brotherhood picks up right where 2 leaves off. So if you are looking for Story, start with 2, however brotherhood has a multiplayer mode, which is pretty decent.
For Assassins Creed 1 No, for Assassins Creed 2 yes.
Assassins Creed Bloodlines is 5 weeks after Assassins Creed 1. This is what happened to Altair before he dies. Assassins Creed 2 is a completely different thing. The main story is the same but the story of the main characters, Altair and Ezio, are very different. Assassins Creed Bloodlines does not have the Animus in it as much as Assassins Creed 1 & 2
yes but buy assassins creed 1 first to get familiar with it.
Branded - 1965 The Assassins Part 1 2-28 was released on: USA: 27 March 1966

Yes. The main character is still Ezio. Edit: Assassins Creed 1 included Altaïr as the protagonist. Ezio was introduced in Assassins Creed 2 and in Brotherhood (2.5). And for your question; Brotherhood does indeed follow the main story about Abstergo Industries.
No, they introduced your Brotherhood in Assassins Creed: Brotherhood.
