Bellatrix Druella Lestrange (Black). We can assume that her middle name is most likely 'Druella' because in Harry Potter the first-born daughter is almost always given the name of the mother as their middle name. And seeing as how Bellatrix's mother was Druella Black (Rosier), it is probably save to assume her middle name is Druella, and that her full name is Bellatrix Druella Lestrange (Black).
Bellatrix Lestrange was played by Helena Bonham Carter.
Molly Weasley killed her after Bellatrix was dueling Luna, Hermione, and Ginny together, and she shot a killing curse to Ginny but missed and aggravated by the death of Fred she doesn't want her ONLY daughter dead so she shot a curse that hit Bellatrix on the chest.
J.K. Rowling never mentioned if Bellatrix had a middle name. However, considering the fact that in Harry Potter the first-born son always gets the father's name as their middle name (Ex. Harry James Potter, Bill Arthur Weasley) and the first-born daughter always gets the mother's name as their middle name (Ex. Ginny Molly Weasley) we can assume that her middle name is Druella, after Bellatrix's mother Druella Black (Rosier).
Andromeda Black- Tonks is a pure-blood witch, the second daughter of Cygnus Black and Druella Rosier, the middle sister of Bellatrix Black- Lestrange and Narcissa Black- Malfoy, the wife of muggle-born wizard Ted Tonks, the mother of Nymphadora Tonks- Lupin, the cousin of Regulus Black, the aunt of Draco Malfoy, and the favorite cousin of Sirius Black. She strongly resembles her sister Bellatrix, but is kinder-looking and has soft brown hair instead of black like Bellatrix's. She is estranged from her family because of her marriage to a muggle-born wizard, and likes cleanliness and casting household spells.

Yes, Bellatrix (Black) Lestrange's sister is called Andromeda (Black) Tonks and Nymphadora is her daughter.
Given that she killed her daughter, probably not.
No. At least, no such thing is mentioned in any of the books.
No. Bellatrix Lestrange and Hermione Granger are not related. Bellatrix is a pure-blood with no children and Hermione is muggle-born. Both her parents are muggle dentists.

Bellatrix dies in a duel with Molly Weasley. She sees Bellatrix shoot a killing curse at her daughter that narrowly missed and she lost it calling her a bitch. She duels her and wins. Her spell caused Bellatrix to explode with the force of a bomb.
Molly Weasley kills Bellatrix Lestrange in a duel, when Bellatrix was attempting to finish of her daughter. This happens near the end of the Battle of Hogwarts, in Harry Potter and thhe Deathly Hallows.
Tonks' mother is Andromeda (Black) Tonks. She is the sister of Narcissa (Black) Malfoy and Bellatrix (Black) Lestrange. Their father was Cygnus Black who has a auntie named Dorea. Dorea Black married a man called Charlus Potter and they had a son. Dorea and Charlus would be Andromeda's great auntie and Tonks great great auntie. It is possible that Dorea and Charlus' child was James Potter but not likely. However the Black family and the Potter family are still releated - however distantly.
Bellatrix has a daughter named Demetra.
