Raccoon kits can be notoriously difficult to raise.
Although Rabies does happen, it is very unlikely in kits. There are other viral disease to be concerned of though including distemper.
Roundworms also affect racoons, and specifically there is one called Baylisascaris. This is infectious to people and can get into the central nervous system of people causing severe illness. (please click to see this link regarding raccoon roundworm infections from the Centers of Disease Control)
It will not be possible of course for me to diagnose the raccoons over the internet. You should know that even in the hands of a trained wildlife rehabilitator these kits often will not survive. Much of it depends on how dehydrated they were when found, how underwight, how long they have been away from the mother, and nutrition they receive under rescue care.
It is also important to note that in many states raising raccoons is ILLEGAL and you can possibly face large fines. It is best handled by appropriate wildlife rehabilitators. They have the experience needed to raise these guys, the equipment, proper nutrition, incubators, and most importantly the area to release them when they get large enough to be released. Raccoons imprint on people, which makes them a HUGE problem when they get older. It isn't just that they keep coming back. In some cases they keep coming back, and become violent. They might even attempt to mate with the previous human owner resulting in conflicts (obviously) and often scratches or even bites.
So, I admire your attempt, but there are many reasons why you shouldn't do it.
