I think that they are overpowered. For example, flying in 4th edition is almost absent from heroic tier, and it starts appearing in paragon tier. Also, no race have darkvision. I'll list the races and say what i think is too powerful.
Cambion: flight(see above); soul mantle lasting until the end of the encounter, especially with the improved soul mantle (+2 to hit every encounter, all the encounter is really very very powerful).Flaming wing seems a bit overpowered (also, it says that it increase damage at 11th level, but it's a paragon tier feat).
Griffon: flight; rending talons is better than a superior weapon proficiency ( compare to the bastard sword, +3 prof, 1d10 damage); the racial power doesn't list how long it lasts (i'm assuming until the end of the encounter, correct me if i'm wrong) and it's very powerful: +2 to hit and extra move action, especially combined with the racial feats
Lycanthrope: this one is fine, regeneration maybe is too much, but i'm not sure. The feat are a bit on the strong side, but scaled back a bit they should be fine.
Satyr: rakish combat advantage is huge; the encounter power is very powerful, especially the "dazed until end of next turn" song; nimble footed is the equivalent of the goblin's racial power, but as a feat; king of liars is huge because of the +4d6 damage part
Vampire: darkvision; by night it gets +2 to hit, +2 to defenses and regeneration 5, that's about 4 levels worth of bonuses. Also blood drain is very powerful, because it makes the enemy weakened and lets you expend an healing surge. Also the feats are very powerful.
It may seem that i'm totally bashing your creation. Well, i like what you have done, they are very flavorful. BUT, they are very overpowered in comparison with the standard races. However, if you and your players are fine with this, there should be no problem.
