Of course they'll get along, Lite. They are the same species (Puntius tetrazona). The 'green' is just a man-made color morph. They aren't different kinds, just different colors.

Usually the established Tigers will accept the newcomers if they wake up with them in the school. If you have enough tank, five Greens would give you 10 Tiger Barbs, which is a good, mellow school; you won't see any picky aggression Tiger Barbs are famous for.
