Hi, is there an option to see damage dealt and or health also a hit area, Like attacker hit victim in the head (99)Health?

Yes, the hitarea/bodypart can be added to a message by using the {bodypart} placeholder for any message which involves a killer (i.e. the player didn't suicide or fall to their death etc.)
The remaining health of the attacker is also available, but only for attackers of the type Player.

More information about available placeholders and configuration can be found on the plugin page at https://umod.org/plugins/death-notes#configuration
