@KairuX3_ If someone is attracted to others regardless of gender they’re Pan!
If someone is attracted to all genders, but has preferences, or views certain attractions differently.
They’re Omni.
If someone is attracted to 2 or more genders they’re Bi.
“parent” works fine as a nonbinary equivalent to mom or dad, but like if they jump in-front of a bullet for you and save your life are you supposed to dramatically say “Parent!” While sobbing into them as they bleed out? Mom and dad have these situations covered way better IMO.
