The first candle was lit on the side closest to the right of the menorah.
Last night (Sunday evening, December first 2013), five candles were lit (plus the extra shamash-candle).
Every day, we place the candles on the right side (so that the candle to the far left is lit only on the eighth night). The candles are lit from left to right, so that the newest candle is lit first. On the sixth night, the two holders on the left side of the menorah remain empty.
The candles (or oil) of the menorah are lit with the shamash (the helper candle), which is positioned on the menorah either slightly higher or lower than the other candles but not on the same level as them.
The menorah is the standard term for the 9-branched candle holder used on Hanukkah. Others call it a Chanukiah or Hanukkiyyah. Each night of Hanukkah, candles are lit to commemorate the miracle of Hanukkah. On the first night, one candle is lit (plus the helper candle used to light the others), ending with 8 candles on the 8th night.
Chanukah candles should be lit after dusk, approximately 25 minutes after sundown. This is the considered best time to light. If one is unable to light around this time or slightly after, it is permissible to light the candles and say the blessings, during the entire evening.
