-kun is an honorific used similiarly as the English "Mr." or "Mrs." There is more information on http://en.wikipedia.org/wiki/Japanese_honorifics. an excerpt for wikipedia:
KunKun (君, in Kanji ?, くん in Hiragana) ("lad", "you") is used by persons of senior status in addressing or referring to those of junior status, or by anyone when addressing or referring to male children or male teenagers. It can also be used by females when addressing a male that they are emotionally attached to or have known for long. Although kun is generally used for boys, that isn't a hard rule. For example, in business settings, young female employees may also be addressed as kun by elder males.
-kun is usually added to the end of a boy's name
Neji kun's father's name meant rays of the sun. *mumbles while tearing up* poor neji kun. T_T
Yuli Kun's birth name is Kun, Yuli Mikhailovich.
It means universe in Chinese and in English it is God.
man
"Kun" is a diminuitive. That is, it asserts a degree of familiarity, or in other cases, social superiority. A teacher may refer to his students, or a boss to those who work under him, with "kun." Likewise, it may be used among friends. It is not only used for males, just as 'chan' is not only used for females. Kun is not something you would attach to the name of your social superiors.
It's obvious when it stands -kun behind the name. Ritsuka-kun is a boy. Well, I'm going to change this answer. Just because the name is Ritsuka-kun doesn't mean it's a boy. It goes the same way for "chan," because it is used for little girls/boys aka Tadashi-chan can be a boy even though "chan" is in the name. the suffix "kun" for girls can be used when a male coworker is addressing a younger female coworker, or when a girl is a tomboy. (ex: Akira-kun) I hoped this helped. :)
Yuni-kun is a name. Yuni is the name and kun is a honorific. Like English has "Mr. Ms. Mrs. Dr." Kun is used by anyone when addressing or referring to male children or male teenagers. So you wouldn't use it to describe yourself unless your name is Yuni and your male.
-Kun is mostly at the end of boys names. Example; Hiroto-kun (Boy)Sorry for not explaining at properly.
