5 Bellatrix Lestrange: The Cruciatus Curse.
Death Eater Bellatrix Lestrange was a well known practitioner of the Cruciatus Curse, where she would torture numerous victims to her immense satisfaction; thus this curse could be assumed to be her signature spell.
One of the charms he uses is the protean charm which we are told in Harry Potter And The Order Of The Phoenix is a N.E.W.T standard spell.
Hermione's bluebell flames
Hermione's magical talents meant she was good at every spell, right from the beginning – Wingardium Leviosa, anyone? But the bluebell flames she once used against Snape became one of her trademarks, and it's also one of our favourites.
Avada Kedavra
It's used to kill people, it's an Unforgivable Curse, and it was Voldemort's favourite, so it's going last.
In Deathly Hallows, Hermione faced a real test of her physical and psychological stamina. After being on the run from a bunch of Snatchers, the gang were taken to Malfoy Manor, where Bellatrix proceeded to torture Hermione using the Cruciatus Curse.

Stupefy since he used it during the fight in the Department of Mysteries or Wingardium Leviosa since he used it to defeat the troll in the girls' bathroom in the first book.
Roughly translated, Expelliarmus – the Disarming Charm – means 'to drive out a weapon' and that's what it does: forces the subject to drop whatever they're holding. Usually that's a wand, which is why it's often seen in duels, and Harry definitely took that to heart, given how much he used it in combat.
Other Favorite Spells
Plus, there were some votes for Obliviate (erases memory), Silencio (silences someone or something), Homonculus Charm (reveals someone's true identity and location), and Levioso (levitation, and some fans say that this is Ron Weasley's signature spell).
Malfoy spots Harry and casts a Cruciatus curse; Harry, defending himself, using the Half-Blood Prince's Sectumsempra spell without knowing its effects. To his horror, it gashes Draco's face and chest, spilling his blood everywhere.
Snape save Draco by using Vulnera Sanentur spell. Sectumsempra is a curse invented by Professor Severus Snape, during his childhood, when he was known as "The Half-Blood Prince. He created it with intentions of using it against his enemies and it soon became one of his specialties."
In the films, Sectumsempra appears as a small flash of white light which causes a cut when it strikes the target. In LEGO Harry Potter: Years 5-7, Harry uses Sectumsempra on Malfoy only to find out the spell has, apparently, painlessly sliced him in half.
I never read it as being the Killing Curse that killed him, but the veil, so it really annoys me that in the movie, they added "Avada Kedavra" and pretty much rendered the veil pointless.
Bellatrix Lestrange (née Black) is a fictional character in the Harry Potter book series written by J. K. Rowling. She evolved from an unnamed periphery character in Harry Potter and the Goblet of Fire into a major antagonist in subsequent novels.
The Disarming Charm became Harry Potter's signature spell, and it notably caused the death of Lord Voldemort during the Battle of Hogwarts by rebounding his Killing Curse because the Elder Wand recognised Harry as its master through the spell connection, and thus strengthened the Disarming Charm to the point that ...
The darkest of the Dark Arts, Harry Potter unforgivable curses are the Cruciatus Curse, the Imperius Curse, and the Killing Curse. Although the curses are highly illegal, Harry using Unforgivable Curses happened, but he uses them once he was thrust into the Second Wizarding War.
Hermione Granger
Her wandless magic can be seen prominently in The Half-Blood Prince. She performs Confundus on Cormac McLaggen simply by whispering into her hand. She also successfully performs Avis and Oppugno Jinx without the use of her wand when sending birds to attack Ron.
Ginny was proficient at charms and curses, capable of holding her own against Death Eaters, including helping Hermione and Luna Lovegood to duel Bellatrix Lestrange. She was even able to cast a full-bodied Patronus, taking the form of a horse and is considered an extremely advanced spell.
Luna is proficient in wandless magic, spell swatting, spell sensing, and occlumency. She can use legilimency.
1 Avada Kedavra Is Just Ridiculous
Only love itself, the strongest magic of all, can block the Killing Curse. Lord Voldemort cast this spell constantly in his lifetime, and it's the spell that killed Harry's parents in particular.
J.K. Rowling came up with one of her patently awesome spell names for Gellert Grindelwald's blue fire spell as seen in the Fantastic Beasts sequel trailers.
Hermione's bluebell flames
Hermione first uses it against Snape when she and Ron think he is cursing Harry's broom in his first Quidditch match. Her bright blue flames set Snape's robes alight, before Hermione scoops them up and puts them into a jar.
