Front Lever raises/pulls
Dragon flag + Variations
Clasp knife (sitting leg raise & crunch combination)
Toes to bar
Leaning crunches (hanging)
Sitting leg raises
I use to mix a couple of exercises for each target/involvement of the abs (not necessarily doing ALL these) working with both crunches and raises (straight and the sides) and also core to target all sections in a workout.
This workout is suitable for street/park/outdoor/home workout, a killer abs & core workout only using bodyweight! Find a bar or anything you can work with for the hanging exercises, also a bench or anything to sit on for those exercises.
Work with the form and step by step before going for the advanced exercises. Be careful with the neck doing the Dragon Flag, therefor its important you work up a good technique first.
To decrease the difficulty level a bit, work with one leg dragon flag, one leg raises etc. Then you can practise that before going for the full ones.
REMEMBER: No matter how good abs you might have you will not get visible ripped abs and the 6 pack abs until you actually work with a proper diet and reaching a lower body fat %.
Extreme ab training combined with eating clean and healthy, discipline with training AND food.
