The effects of multiple Mana Reflections are cumulative. For example, if you have two Mana Reflections on the battlefield, you'll get four times the original amount and type of mana. If you have three, you'll get eight times the mana, and so on.

If an ability triggers “whenever you tap” something for mana and produces mana, that triggered mana ability won't be affected by Mana Reflection.
