Sorry dude but you don't have a prayer of a chance to fix this ! You know anything about automotive electronics , electrical systems ? Have a factory or professional scan tool . Going to advance auto won't cut it .

either gas cap is bad or puge silinoid is bad

Those are both Evaporative Emission Control System related.
442 is a small leak has been detected.
455 is a bigger leak has been detected.
Check all your connections, (electrical & vacuum lines) as well as check for any cracked, loose vacuum hoses in the system, as well as clean "O" ring on your gas cap well and threads in filler pipe & make sure gas cap is tight. Do the gas cap first & see if codes dissappear, but it may take a new gas cap. These codes commonly appear shortly after getting gas, due to cap not back on tight.

Hey, Code 0700-Transmission Control System (Malfunction Indicator Light Request)
Code 1684 -Battery disconnected during last 50 starts

These codes indicate a leak(s) in the fuel system, it can be anywhere, you will have to crawl under and try and see where the leak is, you will need a scanner to turn off the light after repairing the leak(s)

P0442, P0455 AND P0456 are all evaporative leak monitor test failures (small, medium and large leaks). These codes appear anytime the integrity of the air space above the fuel or the lines to/from the vapor canister or purge valve. If there is no damage to the canister, check the lines that run under the van from the fuel tank and canister to the purge valve (under the hood). Also, check to make sure that the hoses are not split or disconnected where they connect to the purge valve. The P1684 is abit more confusing. This is not a valid DTC for your vehicle. It's possible the scanner the shop you went to is an OTC scanner that is reporting a false code. It's also possible they wrote it down incorrectly. The closest thing that makes any sense is a P1486 which would indicate a pinched hose in the same monitor system as the other 3 codes. Best of luck!
