That depends on the year, make, model of vehicle which you did not include. Please ask a new question and more info.
min rotor spec is 26.0mm
Not unless they are under the minimum thickness spec.
For exact spec refer to service manual if figure is not located on rotor.
front min spec is 30.08mm rear min spec is9mm
Minimum thickness is stamped into the rotor. Use a wire brush to remove the rust buildup and you'll see the spec.
Yes, if you measure the rotor thickness, they will be under minimum spec.
To know when to replace your rotors find a minimum thickness from a rotor spec sheet, take a micrometer and measure if below the min. thickness, replace with new ones. This is a fairly hard task to perform so unless you are a skilled mechanic you may want to pay to have this service done.
Jack up the vehicle either both front wheels or one at a time remove wheels probably 19mm socket remove calipers probably between 12mm14mm remove old shoes buy brake clean clean out slide clean out caliper Find rotor minimun thickness spec and measure rotor for minimum thickness have rotors machined or buy new ones reassemble do not damage caliper piston boot do not disconnect brake line loosely install brake reservoir cap have proper brake fluid handy if hard to install new pads use LARGE pliers or C clamp to force caliper piston back into bore feel pedal if spongy bleed brake system reinstall master cylinder cap

Two wheel drive is 18.5mm minimum thickness. If not two wheel drive you can pull the rotors off and they will have the min stamped right there on the rotor.
