Answer 1

From http://tolkiengateway.net/wiki/Council_of_Elrond:

The following people are known to have attended the Council:
Elrond.
Gandalf.
Frodo Baggins.
Bilbo Baggins.
Glorfindel.
Erestor, and several unnamed advisors of Elrond's household.
Aragorn.
Boromir.
Glóin and his son Gimli.
Legolas.
Galdor of the Havens, a messenger of Círdan who just happened to be present at the time. His role in the Council was no larger than asking a couple of questions.

Also, for the 2001 LOTR movie:

The only characters who speak are the protagonists who will later form the Company of the Ring. Unrelated characters (such as Bilbo, Erestor or Gloin) are absent or don't speak at all. According to Decipher cards, some of the non-speaking participants are tradesmen from Dale and Lake-town. Figwit is also present.

Answer 2

For the possible characters I went through 2 sets of trading card to find out about their info, here is the possible list:

Dwarves

• Farins, dwarven emissary
• Linnar, dwarven lord
• Grimir, dwarven emissary
• Thrarin, Dwarven Smith
• Sindri, dwarven lord
• Fror, Gimli's Kinsman
• Gloin
• Gimli

Elves

• Silinde, Elf of Mirkwood
• Calaglin, Elf of Lorien
• Galdor, Councilor From the West
• Golradir, Councilor of Imladris
• Saelbeth, Elven Councilor

Men

• Hugin, Emissary from Laketown
• Járnsmid, Merchant from Dale
• Erland, Advisor to Brand / Erland, Dale Counselor
• Ottar, Man of Laketown
• Jarnsmid, Barding Emissary
• Anborn, Skilled Huntsman

but the best idea might be to go through the film's credit to search for them.

Answer 3

I'm almost 9 years late with this answer, but as much as I know the elf who is sitting next to Aragorn is called Figwit. So the(18.). He's nonexistent in the books and his name was made up from "Frodo is great...Who is that?" He appears later in the trilogy when Arwen is leaving for the Grey Havens and he tries to stop her. He is played by Bret McKenzie who plays Lindir in The Hobbit movies but they are two separate elves.
