I also think most look like Anubias. I did exactly the same thing as you when I first got some plants. Some of the Anubias have leafs that look like Amazon Sword. The problem is, Swords are planted into the substrate and Anubias are not. If you plant the Anubias like a Sword, they will rot and die (mine did, the leaves fell off one by one and it turned into mush.)
Swords have a rather large root system, and Anubias do not (at least not until they are established). I would pull what you think are swords and take a look at the roots.
Another way to tell is Anubias are more expensive to buy than Swords (at least they are here in the US) They are at least double the price of Swords. Not a very scientific way to ID for sure!
Here are photos of two different types of Anubias. You can see how the one looks like what you have. These are both attached to bogwood.
