May question is - what do they do? what usage do they have

You could notice that syntaxes 2,4,6 are "=>{" which means that
what follows next is return value, not body of function, i.e they
don't do what is expected but return delegates which do what is
expected. You need to wrap them into ()() to make them work.
By the way, strictly speaking they are template lambdas.
