>>4 is troll. Boku no Pico and Kodomo no Jikan are two pedophile trapcards that trolls here for some reason find amusing to post.
I'll give you some real recommendations.
But before anything, since you like Ouran HSHC... hmmm... I didn't watched Ouran myself, but I hear it's very close to (and the [strike]butchering[/strike] inspiration source of)
The Melancholy of Haruhi Suzumiya. If want to watch Haruhi, watch everything in the 2009 (chronological) order indicated here:

(Some people will disagree with this, but don't listen to them -- if you haven't read the novels and you want character development to make sense, watch them in this order. If you can't bothered to watch one episode 8 times, then by all means, skip the Endless Eight "arc".)
Most anime you listed are romance/comedy harems. I respect that you liked them, but generally I dislike them and I think you
might change your opinion when you watch somewhat different series (or at least broaden your horizon as a newb and like other things as well).
For example, if you'd like romance mixed with awesome action (in an awesome way) with awesome music, try out
Macross Frontier.
If you're really into harems, you can try out the three staple Key titles: Clannad, Air and Kanon 2006. They are from Visual Novels by the company "Key", and are usually called "crying games" because they rely on making the viewer/player cry a lot in emotional scenes.
