All are correct, but for the first one, I would just say "Let me see if I've got it right" rather than "gotten it right". For #7, I would say "Do I have right?" but not "Do I have it correctly?" Other than that, all of the phrases are great!
If I had just read back what I wrote down, or repeated back the instructions, then I would use one of the past tense phrases. For example, "So your number is x. Did I get it right?", but if I first ask the question and then repeat the information, I would use a present tense phrase. For example, "Do I have it right, your number is x?"
