Kaelyn Gabrielle - Imo, Kaelyn is best kept without nicknames. Some names, and I am having this problem with my own list, seem trying too hard when given an unnecessary nickname. Gabrielle is just a name where there's something about it that completely throws me off. Rate- 7/10.
Isiana Whitney *Izzy* - Isiana is pretty, it's different. I like the nickname Izzy. Whitney is cute. Overall, the combo is cute, I could see it on someone else's child though I could never use it. Rate- 8/10.
Ashley Janae *AJ* - Starting off, I love the nn AJ on a girl. Ashley is cute, though nms. Janae is obviously a name I love as my daughter's middle name is Janae. It really does work great as a middle name. Rate- 9/10.
Aaliyah Audrey ·OR· Audrey Aaliyah - I adore both names separately, but as a pair, they don't flow well together. Of the two, Audrey Aaliyah is the better, but the repeating of sounds honestly doesn't sound good. Rate- 6/10.
Marilyn Eve - I love the name Marilyn. I have bad associations with the name Eve. But I can truly appreciate the name as a whole. The three syllables are balanced out by the single, and there are no repeating sounds. It's lovely. Rate- 10/10.
***
Hayden Dean - I love Hayden, but Dean doesn't pair well with it. The D sound in both names makes it seem choppy. Rate- 6/10.
Andrew Seth *Andy* - This is my favourite name on your list. Andrew is so handsome, and I love the nickname Andy. Seth really works well with it. I adore this combo. Rate- 10/10.
Rowan Lane - As a person with a unisex name and a whole family of unisex named children, I find it very necessary to balance a unisex name with a gender-specific one. I've seen Rowan and Lane on both genders, so I think you should switch some names around. Rate- 5/10.
Austin Michael - Austin is one of my all-time favourite boy names, and Michael is so timeless. I love it, it works on a man of any age. Great pairing. Rate- 10/10.
Kellin Nicholas - Kellin is great, it's a guilty pleasure that I have actually considered using. Nicholas is another amazing one, but as a combination, the K sounds and the I sounds really choppy. Rate- 6/10.
