it has never been revealed if Yamcha has a last name or not.
Yamcha and bulma get together right after goku turns into a great ape in i think ....Episode...... 10
Gohan always use the hairstyles that yamcha has before. despite on their similar looks, They're also portrade by the same voice actor Kyle Herbert.
No one, he didn't get another girlfriend after Bulma.
No, a fusion between Goku and Yamcha would probably make Goku weaker. But if they fused while Goku was a kid, it might be pretty cool. Goyam or Yamku or Goya (FAIL) lol.

No yamcha is not even close to vegeta
Yamcha has not age. This is because Yamcha is not an actual person. Instead, this is a fictional character that is found on the game called Dragon Ball.
As a matter of fact, Bulma actually dumps Yamcha. He mentions it in the episode "He's Always Late", which is one of the last episodes of DBZ. The break up is never actually shown in the anime however.
I think Tien is stronger compared to Yamcha.
Yes, considering Yamcha is human and Piccolo is a powerful Namekian. Also, Piccolo has a braver spirit than Yamcha who can come off a little shallow in some episodes.
Yamcha is a longtime friend and ally of Goku, though he was once a notorious bandit. He is sometimes accompanied by Puar, his devoted cat companion. Yamcha has a great fighting spirit.
No because even though he never knew his brother after a few years, Yamcha is not Goku's brother
Gohan always use the hairstyles that yamcha has before
twice , once by cybaman once when earth was destroyed
Just training
No, not really.
