Looks to me as None of them would light up due to the toggle being open at the top left and the last bottom right one the connection is not complete.

A and K will light up using the top row of batteries if the switch is closed. If the switch remains open they will not light up.
M, P, I, N and G are lit using 6 of the batteries on the bottom. The battery on the left end of the bottom group is not part of the circuit.
Given the phrasing of the question - All The Bulbs Can be Lighted Up!
It just depends if the majority and/or if the all the batteries are charged and there is a closed electrical circuit going to all the bulbs . . . Just Sayin' . . .
"An electric circuit is like a pathway made of wires that electrons can flow through. A battery or other power source gives the force (voltage) that makes the electrons move. When the electrons get to a device like a light bulb, your computer, or a refrigerator, they give it the power to make itwork." (How do electric circuits work? | Discovery Kids)
