What's the difference between suicidal behaviour, self destructive behaviour, self defeating behaviour and challenging behaviour?

Correct me if I'm wrong but:

Suicidal behaviour is when you do things that could kill you or indicate suicidal thoughts like overdosing, crashing your car on purpose etc.

Self destructive behaviour is when you do things that are unhealthy for or harmful to you like drugs, binging, promiscuity etc

Self defeating behaviour is when you do things (or sabotage) to make yourself fail, lose or destroy something that influences your life and bring trouble, like instead of studying you put it off deliberately knowing you will fail--- not sure about this one.. Help?

Challenging behaviour is behaviour that puts the person or people around them at risk or leads to a poorer quality of life (whatever that means) for example people with aggression issues or ADHD have this because they one is a ticking time bomb and the other affects others in school cause they be disruptive and affect both their own and others school progress.

Am I understand them correctly? And please explain simply. Full points to most detailed but easy to understand answer.
