Name check; teammates as a name set

In a fantasy-horror novel with hunting and combat heavily involved, my focal point is a team of six. [name_f]Do[/name_f] the names go well together? Half do not have surnames yet

[name_m]Magnus[/name_m] [name_m]Alexander[/name_m]
[name_u]Valentine[/name_u] Darling
[name_m]Isidore[/name_m] [name_u]Grey[/name_u]
[name_f]Diana[/name_f]
[name_u]Ariel[/name_u]
[name_f]Lilith[/name_f]

Considering renaming [name_u]Valentine[/name_u] and/or [name_u]Ariel[/name_u].

[name_u]Valentine[/name_u] could be a little out of place, but I think as a set of first names they do all work fine together. I can imagine a team with those names. It’s useful that they are all distinct, because it helps know who’s who.

I think all the first names go well together, but only if [name_u]Ariel[/name_u] is a boy. If it’s a girl, I’d change it.

The other thing I would change is [name_m]Magnus[/name_m]'s surname. [name_m]Alexander[/name_m] [name_m]Magnus[/name_m] is one of the ways to refer to [name_m]Alexander[/name_m] the Great, and was the first thing that came up when I googled [name_m]Magnus[/name_m] [name_m]Alexander[/name_m]. In the shadowhunter chronicle books, there’s also a couple named [name_m]Magnus[/name_m] and [name_m]Alexander[/name_m] ‘[name_m]Alec[/name_m]’ and they immediately came to mind when I saw the name.
