I don't really understand what you are askings so I'll answer as best as possible, but stop making a habit of writing like this. This isn't a forum that has many active members that understand poor writing, spelling and grammer skills

What is the 4th's name?

Yondaime, this is said during the series during the battle between the 3rd and oro's versions of the 1st and 2nd. It is not how ever pointed out that technically Yondaime's birth name has not been revealed in the manga or in the anime, so the only name he has is "Yondaime". Yondaime is not only a name but a superstitious pun that makes reference to his fate in the Naruto series. The pun will make more sense if you have knowledge with certain Asian languages. In both Chinese (mostly Cantonese), Korean, and Japanese there are these superstitious number puns. The numbers sound like other words in the language and are sometimes used in combination with other numbers to make a phrase. For example "Yondaime". The thing that makes Yondaime "unlucky" is because of the number four. Four in Chinese, Korean, and Japanese sound like the word "death". Yondaime having the number 4 in his name while utilizing other words that sound like the number "four", basically implies that he's dead, that he should be dead, or other various notions relating to death. To make things worse, in Cantonese if you call him "dai sei" it also means something relating to death, however ... i'm not translating that.

The other Hokage could also be considered a superstitious puns. For example (Note these are written in refrence to the Cantonese dialect.)

* Ichi for Shodaime - 1 sounds like a word which means "guaranteed". In other words, Shodaime's goal of establishing the Konoha village was "guaranteed"/successful.
* Nidaime - 2 sounds like a word which means "easy". Since there isn't any information regarding Nidaime's 'extroardinary feats' if there are any, it is safe to assume that while he was in Konoha, his job as considered "easy".
* Sandaime - 3 sounds like words which mean "birth" and other words which make reference to life. Sandaime was also the one who gave "life" to the people in Konoha by providing them a long period of peace in their village.

What are the names of the people that have signed the Gamambunta scoll?

My memory on that subject is lacking it seems that I only saw three names Yondaime, Jiraiya and Naruto. there are more on there but i didn't look at it hard.


Yondaime and Naruto what is the relation?

*sigh* this Forum has asked me not to say anything until the relation between the two is reveiled. I'm going to hold to that and not say really anything about it. I will say that Yondaime's last name (or real name for that matter) has not been told to us yet, so there should be no ties what so ever at this point.
