Q: What are the directions for the use of these: "extra 2 pieces low side oil checker"?

A: Put the oil checker between your thumb, index finger, and middle finger, and with the A/C compressor running, push down on the low pressure (suction line - which is normally the big A/C line) 2 or 3 times. Set the oil checker upright for 3-5 minutes then pick up the oil checker and check the oil level.
