I dyed my hair very blonde in school, I had no problem with it. Yes, perhaps an additive or bleaching first but that is not a bleached blonde that I've ever seen -- that is a very, very fake blonde that looks like a dye off the rack at your local CVS.
That is 100% not a bleaching, that is dye.
You can't dye black hair a lighter color... It requires bleach.
You can dye it after bleaching, sure. A strict bleach job would trend more towards a whiter blonde than that.
No it wouldn't. A bleach job on dark / black hair would go more orange / yellow. If you want to get 'white' you have to use toner.
To dye hair blonde it requires a bleaching agent.
