Burning 2 conjure candles same planet same day.

When burning 2 conjure candle the same day for same planet. Do you have to have 2 glasses of water and say 2 separate chants for each of them? For example Under incantation for conjure candles for number five in the booklet, can you say what you’re supposed to say right after invoke all of spirits of the # pentacle of planet. Can I say the third pinnacle and then everything I need to say about the third pinnacle and then right after that say the fourth pinnacle and say what I need to say after that or do I have to do two completely separate chants? Also do I just have to have 2 charcoal tablets or is 1 fine?
