I'm guessing this is from Ouran High School? Ahaha. Anyway, Hitachiin, 常陸院, literally means:
常=always/constantly
陸=earth
院=place
However, its origins are thought to be in Ibaraki prefecture, where there is a place called 常陸[Hitachi]. Unfortunately, there is almost no one with Hitachiin as their family name in Japan.
Hikaru and Kaoru Hitachiin are awesome because they are Hikaru and Kaoru Hitachiin. I mean, come on, there probably isn't one person on Earth who doesn't want to be them (or at least one of them).
No, the Hitachiin twins are not gay. Hikaru and Kaoru are just acting that way to get the girls into the club.

Yes. His twin's name is Kaoru.
The Hitachiin twins typially refer to Tamaki Suou as 'tono'. Because of the fact that he is their club 'King' and 'tono' roughly translated means 'lord' or 'master'. It doesn't neccesarily mean that they think he is noble, but it is rather between the lines of SAN and SAMA in the terms of Japanese respect. ! ;D

"Olga" is not a Japanese word or name, so it doesn't mean anything at all in Japanese. Did you mean, "What is the name "Olga" translated to in Japanese?"
