Since Canon introduced the EOS system in 1987, all EOS EF mount lenses will work on all EOS EF (full frame, APS-H) or EF-S (APS-C) mount bodies. This means they will be functional in terms of automatic metering and auto focus.
What field of view each lens will yield on a digital body depends on the size of that camera's sensor. For a closer look at that issue please see What is crop factor and how does it relate to focal length?
Any current EOS DSLR you buy today will be able to use the four lenses you list in your question and give performance at least as good as what you were able to get out of them with your EOS 100 film body.
Many of Canon's newer lenses, however, are much improved both in terms of optical performance and in terms of auto focus accuracy and consistency. A lot has been learned since 1991 when your film camera was introduced! So while a newer digital body can use those old lenses to their full potential, the same can not be said about those lenses allowing a newer digital body to reach its own full potential.
