About what you said about #6 about them looking down on half-blood devils. The Underworld isn't just the 72 Pillars and their descendants. It is full of low-class and mid-class pureblood devils as well. The commoners would far outnumber the noblemen as it in basically every aristocratic world. It's just that we are basically only seeing how some high-class devil of noble origin see things and kind of think that's how the whole Underworld feels. It really doesn't show the perspective of the commoners or show their importance in the Underworld. A lot of high-class pureblood devils of noble origin put themselves above everyone, even the other nobles. And some basically discriminate on anyone not them. I'm a pureblood and you're not, so I'm better tha you. Oh you're a pureblood too, yet you're not a noble so I'm better than you. Oh you're a noble pureblood devil but you have no talent so I'm better than you. Oh I'm of a higher rank than you so I'm better than you. Yeah that.

They might look down on them, but they acknowledge strength no matter who you are or what your origins are. Strength comes over everything you can think of and everything is insignificant in the face of it. If you're a reincarnated devil and have the ability or potential to rise up in the devil world, you will be rewarded and many opportunities will open up to you. For example, Issei basically being planned to marry into the House of Gremory which would make him a nobleman despite being a reincarnated devil. Or Sairaorg basically taking back the position of heir despite having no natural talent and proving his strength. And his father, despite being the head, couldn't do anything about it. As long as you have the strength and opportunity and position, like Issei being the pawn of Rias Gremory, a high-class devil, you will be rewarded.

Now Vali is a special case. The great-grandson of Lucifer, a half-blood devil who possesses Divine Dividing because of his human heritage, and someone who has immense demonic powers. Being the descendant of Lucifer is enough and they just can't turn a blind eye to him. Being a Lucifer far outweighs being a half-blood. The name of Lucifer is that important. And plus he's way too strong to just write off. He would be a major asset to the Underworld. Do you think they would just write that off just because he was born a half-blood? Some of the devils are discriminatory, but they are not stupid. They are very logical and bringing someone like Vali who is the descendant of Lucifer, most likely has an amount of demonic power equivalent to Ajuka and Sirzechs, and is the possessor of Divine Dividing. Now tell me, do you think they would say screw all that just because he's a half-blood?
