Every name has its own meanings, but sometimes it's eerie of how accurate descriptions are. Below is information drawn from various name sources, and then an interpretation of how it all relates to Phantom

Raoul:

"Your first name of Raoul has given you a very practical, hard-working systematic nature. Your interests are focused on technical, mechanical, and scientific things, to the exclusion of interests of an artistic, musical, or social nature. You can be so very positive and definite in your own ideas and opinions that others sense a lack of tact and friendliness in your manner of expression. This names creates a very skeptical outlook on life and rather materialistic standards. You are inclined to be rather self-centered in your personal wants, and your own desires can be so overriding that you fail to recognize or appreciate the feelings, opinions, or desires of others. As a consequence, difficulties in relations within the family or with close associates can arise. In reaching your goals, you are very independent and resourceful, patient and determined. Weaknesses in the health centre in the head, and in the stomach and intestinal organs."

Now putting all this into perspective...

Your first name of Raoul has given you a very practical and hard-working systematic nature that drives your desire to get Christine. Your interests are focused around technical, mechanical, and scientific things, and you show no interests for Christine's interests in music and her appreciation for Erik. You can be so very positive and definite in your own ideas and opinions that others sense a lack of tact and friendliness in your manner of expression. Thus Erik does not want to put up with you and decides to get you into the trap of the Punjab lasso. This name creates a very skeptical outlook on life and rather materialistic standards. Do you really think Christine is an "item" that you can just get? You are inclined to be rather self-centered in your personal wants that you strongly believe a life without Christine cannot exist. Your own desires can be so overriding that you fail to recognize or appreciate the feelings, opinions, or desires of others, especially Erik. As a consequence, difficulties in relations within the family or with close associates can arise. Your brother is not willing to risk your family's reputation just because you would like to marry Christine. In reaching your goals, you are very independent and resourceful, venturing into the cellars on your own if necessary. You are very patient and determined in separating Erik in Christine, without even thinking of your actions beforehand. Weaknesses in the health centre in the head, possibly psychologically for you do not seem to be able to put yourself into Erik's shoes.

Erik:

"Although your first name of Erik has given you a deep, seeking nature, it has also caused you to be far too intense and highly-strung. You could suffer through heart and lung trouble, asthma, pneumonia, speech difficulties or nervous spasms affecting other parts of the body, if not a complete breakdown of the whole nervous system. You are far too sensitive and intuitive and you feel and sense the thoughts and desire of others without fully realizing how you are being affected by them. Feelings of self-consciousness make it difficult for you to express yourself verbally and it is easier for you to express yourself through writing rather than in personal contact with others. Nevertheless, you are clever and have many wonderful ideas, if you could just put them across to those who could further your interests."

And putting Erik into perspective...

Although your first name of Erik has given you a deep, seeking nature, wanting you to explore everything you come across, it has also caused you to be far too intense and highly-strung. You could suffer through nervous spasms especially if you set your mind too much on Christine. You are far too sensitive and intuitive, and you must therefor know that not everyone will feel pity for your face, as well as your actions. You find it difficult to communicate verbally, and thus choose to express yourself through music. You are clever and have wonderful ideas - such as trying to use the Punjab lasso - but you must realize that you cannot undertake brutal actions at your will.
