i am not a car guru but these codes are pretty clear and straight to the point...cylinder 4,5,and 6 misfires...the random cylinder misfire will clear when all misfires have been fixed...

It seems your catalyst is weak ...get ready to replace it or use oxygen sensor spacers for this if you cant afford to change the catalyst at the moment

it also seems your oxygen sensor is weak or bad too..

all codes are related

you might be wrong on the o2 sensor

since we have already a misfire from 3 cylinders in most common cases that will trigger o2 sensors since misfires causes fuel not to be burnt etc the o2 sensors will pick it up and throw a code

so the solution is to sort out the misfire 1st if sorted then clear the o2 sensor code then see if o2 sensor cames back
