Ringtone for each sender in whatsapp I want to give different sound for each sender in whatsapp ( not group ) 
Example: i have 10 contacts in whatsapp so i want each person when send massage i give it different sound means 10 different sound for 10 different contacts. Thank you
This isn't possible. Since WhatsApp messages are (technically) iOS notifications, and WhatsApp (as of now) does not allow this customization within the app itself, you cannot achieve this.
