Sim, todos as luzes estão apagadas.
'Luzes' is a feminine plural noun, so the quantifier must be 'todas'.

Cultural Tip
In Brazil and Portugal, electricity can be expensive, so confirming that lights are off is a common household ritual. In informal speech, you will often hear 'estão' shortened to 'tão'.
