Crop your photos and post them in full size. We can't hardly tell what they are. Go to thread tools and edit your post. Next to the images you will see full size click on it.
I think they are replicas. You may find something on these coins that state that. I hope they are not though. You will find out here for sure.
IMO, the first two appear to be cast. However, your auto-focus has honed in on your background instead of your coins, so we’re unable to see the details clearly.
Theses are way out of my ability to help with. But for taking good photos of the details I can help. First, do not use the zoom feature on your camera. Second, get as close as you can to the coin as possible without distorting the image. Third, take the photo. Then crop everything but the coin. Good luck, hope that it helps you get the answers you were looking for.
Can't tell much from those photos, but my first gut reaction is they are souvenir copies. Welcome to CT and be sure to post what you discover.
Thanks for adding the more detailed pictures. These appear to cast copies. If you look at the two silver-colored coins, both exhibit pitting at about 10:00 (think face of a clock) in the fields on the reverse. These are micro-bubbles caused by air being trapped in the molten metal as it cools in the mold. The gold-colored coin also has pitting near the rim at about 1:30. If you want to be sure, take them to your local coin shop (or 2) for their opinion. In my opinion, they are counterfeit.
