No. The fire belly toads are toxic. They secrete a toxin that will kill the anoles if they ingest it (say, if the toad gets into the water).
Really it's not good to mix any species without a lot of experience, but fire belly toads and newt are especially dangerous.
The turtle will eat both the anoles and the toads when they are big enough, and the toads would poison them.
Besides which, they all come from different parts of the world, which means they need different care.
Each animal needs to have it's own enclosure with the exception of the two toads. You should not mix the same species if you don't have to, much less three different ones.
Oh, and each of those turtles will grow to the size of dinner plates with proper care. Start planning a BIG enclosure each.
