No. An oranda has a big hood on it's head.
Here is a pic of one.
The one in quesiton looks like an ordinary comet, but it seems to have a distended belly. Has it always looked like that? How long have you had it? Is he a very hearty eater?? He might be overweight if that's the case perhaps. But it definitely looks plumper than it should be. Hard to tell with that photo tho.
The red streaked ones are called sarassas, technically they aren't fancy. LOL! But I guess both you and I think they are! LOL! I have a bunch of 'em and they really are pretty because they look koi-like--almost like a tancho koi at times (sarassas are often called "the poor mans koi" because they look like 'em, but are cheap). But they are common and essentially slight abberations of a standard comet (when a white and red/orangey comet breed). The can get fairly large quickly, as they are hoggy eaters. Especially with a 4800 gal pond--you will see them get pretty big.
It is not correct to call it a fantail, by the way. A fantail has a double-split tail.
Here's an example of one. Unless I'm missing something, you have all single tails. But, they are called sarassas.
I sure hope you didn't pay Oranda prices for your "oranda." Because I really don't see how it can be one. It has a single tail, no hood, nor the body shape. They also tend to have very flowy fins. And they swim pretty slowly.
Starting with inexpensive fish is very smart. Most of us did the same, and the fish you have selected are of a sturdy variety, so they should last for years if you maintain proper water quality. If you and your daughter love them, it doesn't matter how much they cost.
Based on what I'm seeing from your photo, you don't appear to have any fish that would not be able to survive the winter in the pond. Of course, there's no guarantee any fish will survive a winter...sometimes, it's just the luck of the draw and if you have a really rough winter or not. And keep in mind that if you don't want the pain of having to drag fish into the house to overwinter, stick to the varieties you already have and avoid orandas and those more delicate fish that can't stand the cold in a pond. Typically (not absolute) those with fancy (double), flowing tails are of that ilk. Watonai, however, would be an exception to that rule. They have double flowing tails, but are exceptionally sturdy. You won't see these in a petstore, however. Very few of us in the US have watonai...they are fish that are just starting to make a comeback in the US. (You might see a sister fish named a Wakin in a petshop, it has the split tail, but not flowing like this. It is more stumpy/squat.) I'm hoping to breed my watonai this coming spring and hopefully have some for sale. Here's a pic of one of mine:
