The customary way to do this is to create new uids, which other people
have already mentioned. However depending on what you're trying to do
it's not mandatory that you do so. For example, in enigmail you can
specify the key to use for an account by its key id, which should work
fine regardless of the e-mail address associated with the account.

OTOH, if you're expecting the people on the other end to encrypt mail
sent to you on one of the addresses that is not part of your key, you
could run into "issues."
