Is there a word for someone who says prayers?
P.S. I googled the phrase "someone who says prayers", assuming that if there were a definition for such a word in online dictionaries, it would be indexed in Google databases, but I got nothing! If the way I searched for an unknown word is not efficient and you know a better approach, please let me know.
Sure, we can say that.
Stop making so much noise out there! I'm trying to take a nap. Let me rest in peace.
Of course, rest in peace is an idiom often applied to the deceased, so such a request may be met with a few giggles. However, there's nothing grammatically or semantically wrong with that request, and its meaning seems clear from the context.
As to how to avoid conjuring up the dead (pun intended), a common idiom is do not disturb, which is how many hotels opt to word it.
So, one alternative might be:
Stop making so much noise out there! I'm trying to take a nap – please don't disturb me.
Or, the peacefully part can simply be inferred from context:
Stop making so much noise out there! I'm trying to take a nap. Please stay quiet, so I can rest.
After all, how else would we want to rest?
We might call such a person an "Overachiever" or an "Enthusiast". We might also call them a "Nutter", "Maniac", or "making us look bad".

There's the word supplicant, but I don't think that can be applied universally.
The word means "someone who requests something," and it can indeed be applied to people who ask God for something in prayer.
However, there are also prayers of praise, and prayers of thankgiving, and I don't think it would be accurate to call someone a supplicant if the person was only offering a prayer of thanks.
A more broadly applicable word would be precant, but it's not a commonly-used word.
