What would be the output of 555 1 second monoshot if I press the triggering push switch for 5 second ?

No.A one second duration, negative going square wave pulse from the the level of Vcc.

Should the trigger be held low, without AC coupling, for a longer duration than the timing cycle the output will remain in a high state for the duration of the low trigger signal, without regard to the threshold comparator state. This is due to the predominance of Q15 on the base of Q16, controlling the state of the bi-stable flip-flop. When the trigger signal then returns to a high level, the output will fall immediately. Thus, the output signal will follow the trigger signal in this case.

jpanhalt said:In other words, if the trigger is longer than the one-shot output pulse, the output will stay high as long as the trigger is low.
