The formula should still work, but you would need to increment by 2 instead of by 1 for each email address that you need to pull out. So:
Trim(Part(SearchAndReplace($EmailList,"-",";"), 2,";")) = [Email1]
Trim(Part(SearchAndReplace($EmailList,"-",";"), 4,";")) = [Email2]
etc
Without knowing how you're using these or how your application is structured, have you thought about having these Emails as a separate table? It would require another table to act as a Many to Many between the Emails and the existing table, but you would have more flexibility in the future. You could also still pull the email addresses up through a Summary field.
