I was searching Bricklink for info about the marked minifigures, but I can't find anything.
I want to know if these minifigures are fake or if these minifigs are in someone set that I can't find.
The figure holding the lightsaber is composed of the head and hair of Anakin Skywalker from the Clone Wars series:
the torso of Luke Skywalker as a Jedi Knight:
The clone figure has the torso of a shock trooper from Ep 3.:
But I couldn't find the helmet.
Zovits identified most items, the missing helmet is a Stormtrooper Type 2 helmet from an AT-AT driver, which is likely also where the legs from the Anakin/Luke mix figure as identified by Zovits come from.
As an added bonus: the torso of this AT-AT driver is used on the middle stormtrooper on the second row from the front, so you have the complete figure.
