Can the Hall sensor face the magnet on the side？

That's okay, too. The Hall sensor is a sensor used to detect the magnetic field, which can measure the strength and direction of the magnetic field near it, when the side is facing the magnet, the Hall sensor can still sense the influence of the magnetic field and produce the corresponding electrical signal output, but the sensitivity and output of the sensor may be affected by the side detection. This is because the active area of the sensor is usually on its front, and the Angle between the side and the magnetic field line is large, so when detecting on the side, the sensitivity of the sensor may be weakened, resulting in a weak output signal. If you need a more accurate measurement, it is recommended to place the magnet in the active area of the sensor, that is, the front of the sensor, to ensure the best measurement results.

Hall sensor side facing the magnet How far away are the magnets?

Hall sensors and magnet spacing is related to magnet strength, strong magnets may cause significant sensor output changes at a longer distance, while weaker magnets may need to be closer to produce a detectable effect.
