Well, it's kind of hard to tell the exact value by looking at the front of the card only. But if they look half-decent on the back you could probably sell them to a low budget collector on eBay or something. You could probably get anywhere from 15-20$ for the shining cards, except the Magikarp which is worth less (because of the condition).
The Feraligatr (Neo Genesis) could probably go for around 5-10$, the Umbreon (Neo Discovery) might be somewhere around 15$, and the Raikou (Neo Revelation) is probably less than 5$ because of the bad condition. I have no idea about the Gyarados because of the foreign language, but the Light Azumarill is (Neo Destiny) is probably around 3$.
The Machamp (Base Set 1st Edition) isn't very rare, because all base set Machamps are 1st editions, except the ones found in a starter deck, which are unlimited and more elusive. It's probably worth somewhere around 10$ I'd guess.
The Mewtwo is not a fake, but from a reprint set called Base Set 2. This set contains cards from the Base Set and Jungle expansions, and as far as I know these cards are worth less than the versions from their original set, and yours is probably worth around 5$.
All of these values are for cards that are average conditions, which means that they might be worth less if they look awful on the back side. But judging from your pictures they look alright, and could probably be sold easily on eBay as a lot.
