None of these is remotely Newcombish. You only get Newcomb paradox when you assume causal loop, and try to solve the problem using tools devised for situations without causal loops.

It is the Newcomb Problem. It may be tricky and counter-intuitive but it isn't a paradox. More importantly The Newcomb Problem does not rely on a causal loop. Some form of reliable prediction is necessary but that does not imply a causal loop.
