Your Answer for Question 1:
It will not work as expected due to set-up time.  The output of the first flip-flop is going to change instantantaneously when the clock edge occurs.  This output, will then become the input for the next fli-flop but there is not enough set-up time for this input to produce a proper output.  If the clocks were not the same however, and the clock edge for the second flip-flop occured an amount of time equal to the set-up time later, then it would work fine.

Your Answer for Question 2:
Elevators use finite state machines to keep track of what floor they are on and they take inputs to see what floor to go to next.

VCR's are finite state machines.  They have different modes of operation such as recording and playing and each mode has their own state such as fast forward and pause for the playing mode.

Alarm clocks are finite state machines which may have different modes such as alarm mode, radio mode, and regular time-keeping mode.
