I understand he is the Falling Angel . But even if it is a big change from Daat to Malkuth , still it is not Qliphoth . So from your quotations Lucifer is the Fallen Angel , is it correct ?
No!
Lucifer is הילל בן־שחר Hillel Ben Shachar, the Son of the Dawn, the light of the world, "the Alpha and Omega, the beginning (Barashyth) and the end, the first and the last," who descends from the Ain Soph Aur (the uncreated light), into Chokmah then into Daath and thereafter into Malkuth, the Physicality of the Initiate.
"And I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit. And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit." - Revelation 9: 1, 2
The bottomless pit is Qlipoth, where the son of the light, mingle himself with our defects, vices, etc., this, in order to die for our transgressions and to save us from the second death.
"Now when Jesus was born in (the pineal gland, that is) Bethlehem of Judaea in the days of Herod the king, behold, there came wise men from the east to Jerusalem, saying, Where is (INRI) he that is born King of the Jews? for we have seen his star in the east, and are come to worship him.
When Herod the king had heard these things, he was troubled, and all Jerusalem with him.
And when he had gathered all the chief priests and scribes of the people together, he demanded of them where Christ should be born.
And they said unto him, In Bethlehem of Judaea: for thus it is written by the prophet, And thou Bethlehem, in the land of Juda, art not (the pineal gland) the least among the princes of Juda: for out of thee shall come a Governor, that shall rule my people Israel." - Matthew 2: 1-6
"I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David (Malkuth), and (הילל בן־שחר Hillel Ben Shachar) the bright and morning star." - Revelation 22: 16
