harry potter riddles!!!!!!!!props involved

i do not own these.but i will give 5 प्रॉप्स to whom guesses each correctly.1 प्रॉप for 1 answer.2 प्रॉप्स for 2 जवाब etc. i'll start of with something easy:

1)one of four
bloodline pure
i listened
spoke
disagreed
and left

if आप hear me speak, आप may not understand
but the last words आप hear were my sole command

i left behind my virtues;my beliefs
and one day
my work will be finished.who am i


2)albus dumbledore had me when he was young and free
years later, he had me a सेकंड time around
आप can have just one but numerous are we
if i am the wrong one, i can end up on the ground
if आप asked me if im small, my answer would be 'yup'
i am so tiny, many of me can fit in just one cup.what am i

3)bifocals rest on the bridge of her nose
rose is the colour of her fingers and toes
i suppose as her fingernails are red
but red hair is not on चोटी, शीर्ष of her head

fleur delacour, elle est un auteur
prestigous शीर्षक debated for sure
one may find her words an offense
others are just made incredibly tense

she bugs many people to whom she's known
her stories are false,their words are not shown
to hold much truth about people and things
'til blackmail forces in honesty's ring

this one has two answers;
4)a married leader and single slave
a toothless elder now gone to his grave
the death for which the younger took the blame
commited द्वारा the one he could not name
they've ten beetween them, ten that do not see
now name the leader and his enemy

5)looks can be decieving
they certainly were with me

betayal and lying
people dying
makes no difference to me

i'd do anything to help him get that wretched boy
it would make my master's empty heartfill up with bubbling joy

much in common i have with him
killed the ones we loved या not

i disguised myself for this man
im doing everything i can

for years and years i endured it all
just to see that potter's life come to a sudden halt.who am i?
