You lost the child tax credit for all of them in the tax year in which they turned 17. From now until you cannot claim them as dependents, you get the $500 credit for other dependents. There is no special federal tax credit for saying that one has a disability, unless you have to pay someone to take care of the disabled child so that you can work--and then you can use the child and dependent care credit--but that credit is not something to enter on a W-2.
If they are full-time college students you can claim them until they turn 24; if they are not students they can be claimed until they are 19. Depending on the severity of the disability, one of them might still be a qualifying dependent after the usual age limit and you would continue to get the $500 credit.
