Slightly longer, but I think refactoring the last few lines to read this way is more readable:

contacts =  salutations.zip(first_names,last_names,addresses)

contacts.each do |contact|
  salutation = contact[0]
  salutation = salutation.is_a?(Array) ? salutation.join(" and ") : salutation

  first_name = contact[1]
  last_name = contact[2]
  address = contact[3]

  puts "#{salutation} #{first_name} #{last_name}"
  puts address
end
