Suggest adding them to https://tools.toywiz.com/keyforge/collection/. It will give you all the main ratings systems: SAS, AERC, EWR, ...SAS: generally anything over 80 is "good" and over 90 is awesome and they get expensive. You can look at other deck prices by SAS rating to get a feel.
EWR: 50% is the middle. Over 60% is awesome.
Of course, ratings are just a guideline, and can be misleading, but generally if you have a SAS <75 or EWR <50, it's going to be hard to win consistently with the deck against good decks (due to lack of creature control, artifact control, fast aember gen, ...)
https://decksofkeyforge.com/ has a great search tool where you can see how similar decks are priced. It only gives the SAS rating though.
Deck 1:
This looks like a good deck. Triple Arise! is great, but you only have 5 Dis creatures to really benefit from it. Bait and Switch is a very important Shadows card.
Deck 2:
Not good, but not worthless. It has a Timetraveller, and those decks used to sell for $20+ but the rest of the deck looks weak.
Deck 3:
Great Shadows deck. Dis looks good too. Logos is mediocre.
