1-3: Pretty plausible and within lore bounds. Tias challenging Nunhs or Nunhs defeating Tia's isn't necessarily a "battle to the death" sort of thing, but if a Nunh gets bested by a lowly Tia, none of his women will be impressed by him anymore so they leave him for the Tia who is now Nunh.
I think a Nunh who is nearly bested by a Tia may take drastic measures to secure his breeding rights in the way you suggest for your backstory. However, if the Nunh kicks the Tias arse, I don't see the motivation for the Nunh to execute the entire family, simply because Nunh's expect to be challenged occasionally - it's part of their culture. If a Nunh was batshitcrazy enough to execute the family of any challenger who faced him for his entire life, 1. no one would ever challenge him, and 2. his female companions would probably all leave him.
4. Wildwood would probably be more common (as those are the Elezen who prefer to walk in sunlight) but a Duskwight is not out of the question because there are a few Duskwight NPCs in the city of Ul'dah. And yes, both Duskwight and Wildwood Elezen use the same "French" naming conventions, just with the caveat that Duskwight and Wildwood Elezen will never share a common surname. Taboo.
5. So Elezen culture, like real world, is very dependent upon where the Elezen is from. Ishgardian Elezen are different from Gridanian Elezen who are different from Sharlayan Elezen etc. Maybe figuring out the backstory or origin of your Elezen Mercenary will shed a little more light on how to base that character. Once you decide, I'd suggest talking to the Elezen NPCs in Gridania or Ishgard or wherever to see how they act and such.
I think the only thing the game suggests is a purely "Elezen" trait and not necessarily based on the society they were raised in, is the fact that Elezen are a very proud people. Big on family and status and whatnot.
Anyways, hope this helps! ^^
