A weight lifter weights 100 Kg and can lift 120 Kg of weight, so why can’t he carry himself and float in air for few seconds??

Adrian Baker's answer was pretty good but I think what you are looking for is "for every action there there is an equal and opposite reaction". In order for a weight lifter to lift a weight, he has press down on the ground with an equal force- no ground, no force, no lift.
