Gita, you said they look great, so why the worries? I do have some bulbs that have been going in & out, making babies, etc, for many years.
See
http://davesgarden.com/guides/... and scroll halfway down, to "When you dig up the bulb..." by the picture of dug-up bulbs on my bench.
Your amaryllises will be fine! Separating the bulbs is a good way of having extra "insurance" in case one of the bulbs has trouble down the road... also, potting them individually can let you keep them cooler and bring them upstairs to enjoy one at a time, extending the show all winter.
