cause It's really hard to find
Sir Perceval and Lancelot both attempted to obtain the grail, but neither was successful. Sir Galahad ultimately succeeded in finding the Holy Grail, and was permitted to gaze upon it, but never actually brought it back to King Arthur's court.

Well, not really. For one, the biggest problem is people who search for the grail don't know what it really is. There are lots o possibilities of what the holy grail might be. So nobody ever recorded finding it. Many orders and groups proclaim they have the holy grail but nothing can be proven. So to answer your question, nobody knows, maybe somebody did, or it could still be hidden.
The search for the Holy Grail.
Well that depends on what you think the holy Grail is. Some believe it is the cup Jesus drank from (which means it was used by Jesus at the Last Supper) and some believe it is the Virgin Mary herself.
Because he was arrested as well.
Sir Lancelot looked for the holy grail, unfortunately he never found it

That depends on who is telling the story. In the earliest versions of the story, it was Sir Perceval. Later romances made it Sir Galahad. At least one medieval German work has it be Sir Gawain.
Lancelot and Galahad were much different. They were both amazing knights able to best most others at anything because of their skills in fighting. However, Galahad proved that he was the better knight by defeating Lancelot on the quest to find the Holy Grail. Galahad was more pious than Lancelot and it was his purity that allowed him to be the best. Lancelot had been considered the best knight but then, because of Lancelot's sinfulness Galahad was able to best him. Galahad also seemed like he was not human to many people because of his great holiness. Lancelot had made mistakes, but eventually had repented; Galahad didn't seem to make any mistakes and was able to reach the holy grail, while Lancelot was only to get a glimpse of it.
