In Japanese, there are many honorifics that you will need to use. I will show examples of them using my name.

NOTE: NEVER INTRODUCE YOURSELF WITH AN HONORIFIC! DO NOT CALL YOURSELF (name)-CHAN WHEN INTRODUCING YOURSELF!

-San: Essentially the Japanese equivalent of the English "Miss" or "Mister." It is an honorific that shows the proper level of respect in most situations.
EXAMPLE:
My name is "Oh Angelica" (First name before last), so you would call me "Oh-San".

-Chan: A "cute" honorific, this is used mainly for girls or young children, but can also be used to address pets, and even lovers. It expresses endearment and affection.
EXAMPLE:
Angelica-Chan

-Kun: The honorific used for boys. It is sort of a less-cutesy version of -chan. It can be used with boys your age or on boys who are younger than you or in a lower position.
EXAMPLE:
Aki-Kun

-Sama: Indicates a very high level of respect for the addressee. Appropriate for use when talking to somebody on a higher level than you are.

-Dono: "Lord." Indicates an incredibly high level of respect, but only used on males.

Sempai/Senpai: Used to address people of higher age, mainly in a school setting.

-Bozu: Used to address children. It is far less "cute" than -chan, and is similar to the English "squirt."
EXAMPLE:
Angelica-bozu

-Kohai: Used to address lowerclassmen.

-Sensei: Honorific used on teachers, professors, instructors, etc.
EXAMPLE:
Oh-Sensei

No honorific: Lack of an honorific shows extreme closeness between the speaker and the addressee. Honorifics are normally omitted when addressing family, very close friends, or lovers.

Here are some more.

As I begin to go through this thread, I realise that a lot of the information here is incorrect. Thanks, uber-tired me. You done great.
I'm going to start a V2 with more accurate information, posts will have sources, I'll help provide links that will help users learn Swedish, (But I won't teach users directly) there will be more posts, hopefully, and other cool things, too.
Can't wait to see you in V2!
