What are considered normal readings for the front and rear O2 sensor readings??

bank one's voltage should should dance up and down rather quickly.
no idea on the rear o2, in the early years it dont do much.

Front will fluctuate from say 100 or less to 800 or a little over.. then some in the midst.. The faster the readings change the better.
Never honestly looked at a rear sensor reading.

If you look at a rear sensor on a graph it should remain steady if the cat is doing its job. If not it will fluctuate like the forward 02 sensor
