Try Diabolik Lovers :D ^^b good luck~oh and do you prefer shojo animes?

Not really, but here's a few that I think you would enjoy though, due to them having the same atmosphere as some of the ones you've listed.

Princess Tutu (Seems like a kid's anime, but it's well written and the characters just manage to captivate you really easily), Kaleido Star (This one's more about friendship and following your dreams, but the animation is pretty good for the time period that it came out in, and it has just enough laughs and drama to make it really fun), Lovely Complex (Cute romance about a super tall girl and a super short guy, both of whom are funny as heck), Fruits Basket (Anime's pretty good, but the manga is hands down one of the best manga I've ever read), Kimi Ni Todoke (Probably the cutest manga/anime I've read/seen) and you might like AKB0048 (It's a girl only anime for the most part, but it's pretty heavy on the friendships, music is good, and the animation is great too) as well.

Kuroko no Basket and Big Windup! might be up your alley because you've seen Free! Both are similar to Free! in the aspect when it comes to friendship and whatnot, but are a bit more sports driven than Free! was. However, I highly recommend both of them.

And just to put a few more in for fun that you might enjoy is Ghost Hunt and Natsume Yuujinchou. The first one's a bit horror related, but the writing is good, and it's one of those animes that once you start watching, you can't stop watching until you're finished. Then NY is probably the sweetest and most heartfelt anime I've ever seen and seriously underrated, but it's awesome and will probably make you cry, laugh, or do both at once.
