Depends upon the motor and its load. Some are less. Compressors tend to be
a lot more. Check the nameplate on the AC. Look for "LRA".

Momentary dimming of lights on motor starting is quite normal.
If it is a 120V motor, the lights on circuits on the opposite
may brighten. Some lights are more sensitive to voltage
fluctuations: lights partially dimmed are much more noticeable;
full on incandescents are less noticeable.

What does LRA stand for? An acronym? Name of a manufacturer?

That should be "Locked Rotor Amps", the maximum possible current
drain.
