No. In prayers they refer to hundreds or one hundred or even a thousand ("You who pass by here say 'a hundred loaves of bread for the ka of ...'"). Never saw a number in a prayer or funerary text that wasn't a round number of hundreds or thousands.

No. There is no evidence of an interest in numerology or gemantria.

No.
