those are classic vacuum lean codes indicating an upper intake air leak. Look and or test for leaks after the MAF in the engine bay. Cracks in hoses and or worn and brittle gaskets. You can complete a smoke test to help find them easily or spray some carb cleaner around the hoses while the engine is running, and if the idle increases, you know where it is.

Try and Google what the codes mean by the year make model and engine size you should be able to get a clear answer for each code and possible how to fix or to test to be positive that is the correct problem to begin with some codes can be triggered by another sensor that might be malfunctioning but it's still reading that it is good
