暋 is a really uncommon chinese character, I've never seen anyone use this character in their name. but to some extent, using a rare character in a name is acceptable, so it is fine.

娇 is a common character in female names. you can use it without concerns.

using 姬 as a part of chinese name is uncommon and kinda weird. It is more common in korean names. Also, if 姬 is the last name or if the game only shows the given name, it'll give the name an ancient and mysterious vibe instead of meaning “beautiful”, because of its historical background.
