In the last question. When the switch is turned on, all the lamps will light. In a series circuit, the first lamp will be brighter and the second will be dimmer due to the voltage drop. In my opinion, the correct answer is 4. Answer 3 is correct when L3 is inoperative.
In switching bulbs question ... I'll first switch ON the first bulb and then I will keep it off then I'll switch on the second one and then quickly turn off and I will enter the room by touching the bulb I can feel the heat which one will be too much hot that is switched first , less heated one is switched second and the cool bulb is the 3rd one

L1 and L3 would be the only one to light up since current will flow through those light bulbs
L1 and L3 will light up if those switches were closed
