As I said before, it's already been explained multiple times in this thread. You obviously couldn't be bothered to read it, so I'll recap it for you since you are paying attention now.
The word 'roshi' in Japanese literally means 'master.' In Japan, when you have an authoritarian situation, ie, student > teacher, employee > boss, ect, you don't address them by their actual name, you address them by their title. Master Roshi's name isn't Roshi, that's his TITLE.
But stupid Americans who don't understand honorifics in language translated the word roshi as his name, and not his title. So they call him Master Roshi (which is actually redundant) instead of just Master like they are supposed to.
So in Naruto, the Jinchuriki is once again addressed as the 'master' of his bijuu, but the fans who translated it to english didn't pick up on the fact that it's his TITLE, and not his NAME.
The four tails is a giant ape, name Son Goku. One of the four main characters in the 16th century epic is called..... Son Goku. He is a monkey, and Son Goku literally means 'monkey king' or 'king of the monkeys.' The number 4 is significant to Journey to the West because the novel itself is one of four great stories in ancient Chinese literature.
The number 4 is also significant to the story Journey to the west as there are 4 main characters and Son Goku is one of them.
Do you understand yet?
Looking at the panel that was referenced to have krillin and chaozu on it, the scene takes place in front of a 'cosplay' stand, where Naruto is looking at a mask he wants to buy. A couple of the other people standing around are dressed up, one of them wearing monk attire and the other one wearing clown or mime attire.
The coincidence is that both Kishi and Toriyama used characters in their manga that are extremely popular in eastern asian culture.

I don't know how else to explain it to you, but you've obviously decided that Kishi is copying DBZ. You couldn't be any further misinformed.
