Can you help me with this code if you click the button once the LED will turn on and if you click twice the buzzer will turn on and if you click the button three time the LCD will print "ON" this could be the code?

You can only have one setup() and loop() function in your program. Get rid of one and see what happens.

Since you set c to b+1 and all b ever is is 0 all c can ever be is 1 so only the first thing can happen.

Is that your problem? You never really said what the issue was.
