Nii-chan means Brother so i guess it means that he looks up to him and see him as a big brother in a way!!
Though it is stated by Souta to his school friends that Kagome married (she is shown back in the Feudal Era, so she presumably married Inuyasha), they are never shown in any form of the canon as having children. While it is entirely possible that they do, speculation as to how many is just that: speculation.
It is unknown in the anime although Mrs. Higurashi says he proposed to her under the Sacred Tree. Also in the first Inuyasha movie (Love that Transcends Time), when Kagome's mom comforts her and tells her that the Sacred Tree has been with them for a long time she says it has been with them through sad times (in the flashback it looked like they were in funeral clothes). In the Shousetsu Inuyasha (novelization) book, it tells brief history about the Higurashi family. After the father died because of an accident many years before, Kagome, along with her mother and younger brother Souta moved into the father's parents' home, which was the residence on the shrine property. Jii-chan (Kagome's grandfather), who was the shrine's caretaker, was alone after his wife passed away. That is why the mom calls Jii-chan grampa instead of father, why they live on the shrine, and why the dad is never seen. The reason why Kagome and Souta don't feel as bad for his death is because they were still little kids back then and they didn't get to know him as well as the mom did. I'm not sure if the Inuyasha novel shows his face either. I hope this is enough information to answer your question and any others.
Inuyasha
inuyasha picked kagome
Inuyasha the Final Act is the newest season of inuyasha.
It's Episode 82, A Gap between the Ages.
His grade is never actually mentioned in the Final Act.
Ichida Souta was born in 1843.
Ichida Souta died in 1896.
Yes, since its 2010, it is new anime for Inuyasha. Its call Inuyasha: The Final Act.
they almost kiss in episode 18 of the final act (souta burst into kagomes room right when theyre lips are like a micro meter away) and they kiss in episode 26 of the final act
niichan is for an elder brother (chan is informal you use it with someone you are close to like kun san is for someone who is a higer rank then you like your boss)
Ginta ,and Hakkaku
no one really knows. but since his father's name was Inutaisho, and in fanfictions and what not they call InuYasha, InuYasha Taisho. That's my closest offer

In the manga, it's stated that Inuyasha and Kagome have married following the events of the final arc. However, it isn't stated how recent that marriage is, and no children are shown.The anime's television run ended before the final arc was drawn for the manga; however, in the Kanketsuhen (The Final Act) series, Souta tells his school friends that his sister has "gotten married and moved away," and Kagome is then shown in miko robes, back in the Feudal Era with Inuyasha. As in the manga, there are no children shown.
