If I'm honest, i'm not overly keen on any of them.
I like Alyssa, but not Skylann.
Kaylee - im neutral, but not keen on Jenelle
Stephanie - bad association. Not the names fault. Kaelyn, the spelling puts me off
Haylee Deema - I don't like the 2 x ee and not sure about Deema. Hailey looks better to me too. What about Hailey Makenna?
Trinity Makenna seems like the best match of the bunch and by far my fav. =)
Not making fun, but honestly they all seem a little trendy to me...mainly because of the spelling. I'm not a huge fan of using an e where traditionally people would us a y like in Haylee and Kaelyn. I'd probably say that the first names I think are best of the bunch are Alyssa and Stephanie, but I'm not wild about Skylann or Kaelyn. My least favorite by far would be Trinity. Way too trendy for me.
I don't like any either, sorry! If I had to choose I would go with Alyssa. My main issue with the names is the spelling. I think if you used Haley or Hayley it would make a big difference. Haley Makenna would actually be quite sweet. I think you should ditch Skylann though. It reminds me of Skyrim and seems a bit like a trendy smoosh. Are you after more ideas? If so, how about:
