Here is a nice lightweight indicator by Mladen called iClock which can be used to display different candle and bar times remaining.

To add more than one, just add another iClock indicator to your chart and add an additional number or character to the "UniqueID" section in the indicator's options.
So instead of iClock1 name it to iClock2 etc.
You can then stack the displays above each other. Positioning is totally customizable.
