I don't think so but not many people have seen them i think
He hasn't shown any romantic interest in anyone.
No.... If you look up naruto shippuden ending 10 it is shown that she has a rather tiny figure.
No, Naruto doesn't have have a sister
Yes, During the 'Ultimate Weapon' arc (plus/minus episode 216-220 [which is the Naruto fillers that are not related to the original story a.k.a Naruto manga]. During these episodes the sand village took on Konoha (leaf village)-ninja academy training style/method, the 'sand siblings' being the senseis/instructors. None of the students were brave enough to choose Gaara as their teacher, except for Matsuri etc.Surprisingly enough she is not only shown in the fillers; She eventually made an appearance in the manga (chapter 280 [part two]) and in part two of Naruto (Naruto Shippuden) during the 'Rescue Gaara arc'.*To read more on Gaara or Matsurihttp://naruto.wikia.com/wiki/Gaarahttp://naruto.wikia.com/wiki/Matsuri(warning: links do contain spoilers)
To add on to it being unclear if his affections still lie with Sakura, in the anime there has been some glimpses into Ten Ten having some romantic feelings toward Lee. Now when you go by "love," he doesn't romantically love him. It can be shown that he loves him as a close friend. Similar to the relationship held with Naruto and Gaara, or even Naruto and Sauske. Naruto did everything he could for both of those two. Lee hasn't had as much of a chance to help Gaara anyway except for when Team 7 and Gai's team go on the first mission during the shippuden seasons. The times we see Lee have contact with Gaara is very minimum so its difficult to truly answer that question. But romantically I do not believe so. No, Lee doesn't "love" Gaara. They become friends sometime after Gaara reforms. As far as romance where Lee is concerned, his affections lie with Haruno Sakura, but it is unclear at this point if he still has romantic feelings for her.
I don't think he shows much love to anyone, but there is a girl in his village that likes him and he as stronger then average feelings for.
No Gaara is not bad. In the first Part of Naruto, however, he was described as a very selfish person. But Naruto influenced him to be a better person, which Gaara's change of mind is shown at the beginning of Shippuden, so he is not bad.
The sealing of the Sukaku into Gaara has yet to be shown.
He hasn't shown any romantic interest in anyone.
Probably spring 2009
the two-tailed beast
Nothing really. She's not shown.
Answer As of May 7th 2009... they have shown 108
Besides Itachi having sasuke as a little brother there are no relatives shown in naruto to any other akatsuki mebers except for sasori they have his grandmother and his cousin(gaara IS sasoris cousin belive or not!)
Its not shown in manga.
His murder was presumed to happen some time before the Chuunin selection process started, so Orochimaru could take his place and begin his plans to use the Hidden Village of the Sand to help destroy Konoha. The actual killing though was not shown until episode 127, as part of Kimimaro's back story.
No uniform for Suna medics has been shown.
