I'm compiling a name list for another thread:
http://forums.startrekonline.com/showthread.php?t=141661
I'd love to have a friendly list and a hostile list of factions (they can appear on both lists, sometimes)
As of right now, for Federation only, I know of:
Hostile
Borg
Klingon
Undine
Cardassian
Dominion
Romulan
Orion
Mirror Universe
Hunters
Reman
Hirogen
Nausican
Gorn
Lethean
Friendly
Klingon
Bajoran
Ferengi
Orion
Andorian
Vulcan
Trill
Benzite
Bolian
Saurian
Betazoid
Cardassian
Romulan
Can anyone else think of factions (currently in game) that I missed?
Comments
Various species you encounter via exploration missions, both hostile and friendly.
Reman
Hirogen
Friendly:
Tribbles (how could you forget them?)
Nausicans
Gorn
And then this link, but I think OP has covered many on this page:

- Lieutenant Commander, Grade 1, Felspar Que'toc Gemmina
U.S.S. Eurynome
Cardassian
Romulan
The main Cardassian government is friendly with us, but the rebels are against us. The same goes for the Romulans, some are against us and others are friendly with us.
Benzite
Bolian
Saurian
Betazoid
Hostile;
Lethean
