it could be sinularia, or nephthea, or a number of others. The vast majority of soft corals have not been described/identified scientifically, and those that have been can only be positivly IDd by microscopic views of their sclerites. Even two groups that many people claim to be able to tell the difference between- Sarcophyton and Lobophytum- have recently been proven virtually indistinguishable under intensive identification studies.
Point being- it is essentially impossible to get a positive ID, even to the Genus. Kenya Tree, Colt, Finger Leather, etc are all just layman terms that describe the shape of the coral (well, I guess colt doesnt look much like a young horse, but you know what I mean). What you have are two branching soft corals with a green tint. The second one has some characteristics commonly found in corals from the Family Nephtheidae. The green color indicates that they are likely to do best under moderately stong lighting and moderate to high water flow.
Worth depends on where you are. I know people who just give away cuttings of these types of corals because they grow so quickly. In a retail setting, your colonies would probably get $40 to $70 depending on the market. 4-5" frags may get you $10-$20 at a frag swap or something similar.
