Decide a name for me

I need to rename two characters, so please let me know which of these names you prefer! I'm especially looking for names that are pronouncable in Mexico as the characters are Mexican, and I'm not looking for new suggestions. Please choose one name from each list.

Saanvika, Sudiksha, Sanvika, Sathvika, Sayantika, Saatvika, Sasvika

Sriansh, Shivansh, Sarvesh
