Whenever they release official footage of ingame stuff, I usually don't look at the names as they're usually "XIV Conjurer."

But the 2.0 screenshot has some nice fan service in it: http://wdl.square-enix.com/ffxiv/download/en/FFXIV_2.0_Specs_EN.pdf

The party members are:
Delita Heiral
Kain Highwind (title: Dragonslayer)
Faris Sccgerwiz (title: Scourge of the North)
Boco (title: Delita's steed)
Vivi Ornitier
Yuffie Kisaragi (title: materia hunter)
Romeo Guildenstern (from Vagrant Story. Title: Ladykiller)
Agrias Oaks (has a tittle but it's cut off: Maidens of the Gra...)
