It should be possible to use one set of Oracle binaries for multiple Oracle instances, I think - somebody please correct me if I am wrong. Unless it was a very strange situation, you would almost certainly need to have one copy of the identical binaries in identical locations on each of the three nodes though (or one copy on NFS, or a cluster filesystem that was globally accessible), so that really wouldn't be one copy of Oracle binaries, I guess.
That said, I have generally not done that for the following reasons: 1) Disk space keeps getting cheaper and the binaries don't take up that much space (relatively speaking). 2) People virtually always forget to make changes (e.g. patching) to all three nodes equally - they patch one, or something like that, and they always get out of sync. For this reason I generally prefer the binaries on shared storage, failing over with the data, but there are valid reasons not to do it this way too. 3) Someday someone might want upgrade for one of the instances, but not the others. At that point you have the possibility of some screwing up one or more of the instances you didn't want to upgrade. As for the Database Agent Configuration Wizard, I don't know because I never use it. It may be expecting to put the binaries under cluster control and fail them over, and when it tries to do that for a second instance, it notices the conflict and flakes out, but I would hope it would have sense enough to emit a meaningful error message rather than throwing a bunch of Java exceptions.
