The styles are a bit jumbled to me: on one hand, Felicity, Verity and Nicholas go great together, with Andromeda and Sundance particularly being the outliers. I do like the virtue-middle-name theme you have going on, though!
Andromeda Hope - 8
Felicity Grace - 9
Nicholas Justis - 5 (the repeating ending sounds make the flow off, just a bit)
Verity Faith - 5 (this is a very wordy and descriptive name, which is not to my taste)
Sundance has a really beautiful sound, but it also has a very important meaning to Native Americans. Here’s a quote from another thread about Sundance: “The Sun Dance Ceremony, from which the name Sundance is derived, is the most significant religious ceremony of the plains tribes of North America” from this thread (Sundance Sibling - #11 by hellobanjo). I would definitely look into this name more and perhaps try to find alternatives.
