Kaelyn Gabrielle - I don't like Kaelyn. It looks made-up and trendy, and nobody would be able to spell it. Also not a huge fan of Gabrielle, but it's not terrible. The flow is pretty good. I would prefer something like Caitlin Danielle/Caitlin Daniela. 2/10
Ashley-Janae Marilyn "AJ" - I'm not a fan of hyphenated first names, and as the above poster said, Ashley-Janae is pretty unwieldy, especially with the added middle name, Marilyn. Just Ashley Janae would be better, or even Ashley Janae Marilyn. If you must hyphenate it, a shorter name would be better, i.e. Ashley-Jo. As for each individual name: Ashley, I prefer on a boy. I've heard it on a girl tons of times, so it's underwhelming. Janae is along the same lines as Kaelyn; it seems made-up. Marilyn is nice, but not one I'd use myself. I'm also not crazy about the nickname AJ. 1/10
Audrey Victoria - I like Audrey a lot, though it is very popular now. Victoria is also very pretty, and the flow of the combo is great. 8/10
Isiana Eve "Izzy" - I really don't like Isiana. I've never heard it before; it seems very, very made-up. Isabel/Isabella or Isadora would be 100 times better. Eve is pretty. The flow isn't great. I do like the nn Izzy. 1/10
Rowan Alyssa "Row" - I like Rowan. I don't care for Alyssa, but it's a nice combo. I don't like the nickname Row; just Rowan would be much better. 6/10
Hayden Andrew - I'm not a fan of either name, but it's an okay combo. 6/10
Dean Hardy - Again, not a fan of either name. It kind of sounds like an old TV host. Unless your last name is long, I'd prefer a longer middle name. 5/10
Kellin Matthew "Kell" - I'm not a fan of Kellin- I went to school with one, and he was't my favorite person. Matthew is nice, and the combo flows well. 6/10
Austin James "Aussie" - I'm not huge on Austin, and Aussie doesn't improve it. I sort of agree with Addison; it seems a little weird, since Australians are often called Aussies. James is nice, and the combo is pretty good. 7/10
Adam Jacob - This is nice, but not anything special. I can't say anything bad about it. 8/10
I'm sorry if some of my comments seem rude. I tried to be as honest as possible without being harsh. We have very different naming styles.
