Dives is not a name. It is a Latin adjective which simply means rich. This is how the tradition evolved which gave the rich man the name of Dives. If wealth prevents us from getting into heaven, then Abraham wouldn't be the one meeting Lazarus because he was a very wealthy man. The rich man does not end up in torment because he is rich, but because of his indifferent and uncaring attitude toward poor Lazarus.
