Unfortunately, the Ministry of Magic thought that the sword didn't belong to Dumbledore in the first place, so Dumbledore had no right to leave it to Harry. The Ministry confiscated the sword, which was in the Headmaster's office at Hogwarts.
Question number one: Why didn't Dumbledore just give the sword of Gryffindor to Harry instead of leaving it to him in his will? He knew even before his death that Harry would need the sword to destroy Horcruxes, and he must have known that the Ministry would not let Harry get the sword.
Dumbledore wanted the power of the Elder Wand to die with him, so that such a potent weapon would be no more. Because you can't just give someone your wand.
In addition, the portrait of Dumbledore told Severus Snape that the sword must be taken under conditions of need and valour, which was why Snape put it into the frozen pond in the first place.
Why didn't Dumbledore teach Harry how to destroy Horcruxes?
Dumbledore Never Really Had Time To Explain How To Destroy The Horcruxes. As much as Harry would have benefited from Dumbledore's knowledge of how to destroy the remaining five horcruxes, there was simply not enough time before his death to do so.

Did Voldemort realize Harry was a Horcrux?
On his quest to reach immortality, Lord Voldemort created horcruxes, but he didn't know he accidentally created a seventh: Harry Potter. In 1997, readers were introduced to the Wizarding World in Harry Potter and the Philosopher's Stone, the first novel in what would become a series of seven books.
Dumbledore knew about Horcruxes. He knew how they were formed, what happened after that, etc. He probably got to know Harry was a Horcrux when he saw the Scar on Harry's forehead, but maybe he wasn't sure.
Since goblin metal takes in only that which makes it stronger and rejects anything that would weaken it, Gryffindor's blade couldn't have been turned into a Horcrux. Likely, the soul fragment would have been rejected, which could have seriously impacted Voldemort's plans in Harry Potter.
Why did Snape put a fake sword in Bellatrix Vault?

Honestly, Hermione knew Dobby was a lost case... nothing could have revived Dobby after the attack or she would have definitely helped Harry with Dobby considering she was the girl who started S.P.E.W(Society for the Elfish welfare) and fought for elf rights. There was nothing to be done at that point.
His dad gave it to him. To elaborate on Icecreamdif's answer, he inherited it as a family heirloom dating back to Hardwin Potter, who married Iolanthe Peverell, granddaughter of the Cloak's original owner Ignotus. It was passed down to the eldest male of each new generation of Potters since then.
The headmaster had never anticipated being so weak when Draco Malfoy confronted him, and the boy was, therefore, able to disarm him easily. Dumbledore must have been terrified when his wand was flung from his hand since he would have recognized that this meant its power wouldn't die with him after all.
Narcissa's love also drove her to lie to Voldemort himself, which was instrumental both for locating Draco, and for Voldemort's final defeat at the hands of Harry Potter. This also indirectly ensured Harry was protected again by a mother's love.

At some point in time, Lord Voldemort gave Bellatrix Lestrange Hufflepuff's Cup, one of his Horcruxes, to keep safe in her vault, though he didn't tell her its true nature.
Lord Voldemort was unaware that this Horcrux had been destroyed, until he forced the truth out of Lucius Malfoy (who did not know the diary was a Horcrux) shortly after his return to power in June of 1995, due to the portion of the soul being separated from his body for such a long time.
The simplest explanation of Hermione's resistance to the Horcrux's effects is her superior mental strength. Hermione proved herself once again when she withstood Bellatrix's Cruciatus Curse.
Why did the Elder Wand belong to Draco and not Snape?
This nuance was lost on Lord Voldemort, who wrongly assumed Severus Snape held the Elder Wand because he was Dumbledore's killer, when in reality Draco had disarmed Dumbledore before Snape arrived on the scene, making Malfoy the wand's true new owner.
