It looks like all these codes relate to the evap and purge valve? Is there an easy fix for these?

 

P0457-I'd first make certain gas cap is tight and if the code has been on for some time, I'd replace the gas cap, then have the codes deleted. If no way of deletion, just drive normally for a few days and if the light remains on have the codes checked again.
The other 2 are related to the purge control solenoid/stuck open/ inoperative and/or no tank pressure.
Given some time after cap replacement, and if code(s) still on you'll need to look into the purge control solenoid. From what I can see, that can be tested by attaching a hose to the solenoid, apply vacuum, see if it holds, then run 12 volts to the solenoid to see if it works and if so, the vacuum will drop.
