Ears are simply internally; laughably so, even. It's really not much of a stretch to modify the sinus pathways in order to accomodate an extra set.

Horns and scales? believe it or not they're composed of either kerating (hair) or bone.

Most kinds of tail a human body can accomodate the same way our evolutionary ancestors once had them; we've technically got a tail bone on our spine, it's just tucked away inside since we don't need them anymore.

Wings, however, aren't like ears, horns, tails (hell even the fins on some fish faunus wouldn't be that complex, but i'm not that well informed on fish so i couldn't explain it.)

The reason wings are a problem, and why I find them utterly ridiculous, is both simple and complicated. Basically, wings are arms. Bird wings evolved from the arms possessed by their reptilian ancestors (the dinosaurs), the surprisingly powerful muscles used to move them down while flapping are anchored onto their sternum, which is larger and sturdier than the sternum of similarly sized mammals in order to support the extra strain.

Theoretically if a bird faunus had wings in place of their arms, it could work; the muscles that was use to move our arms are roughly the same as a bird uses to flap, just built a bit differently. This is why birds can move their wings around the way they do while cleaning them.

The problem really comes in when you attach wings to the back of a humanoid torso. See, wings, like your own arms, are connected to the torso by muscles, tendons, and bone; specifically a ball and socket joint, the same as your shoulder or hip. The problem this produces is that you need substantial additions to the skeleton in order to support an entire extra pair of limbs a bipedal humanoid body just wasn't designed to have. The muscles would need to go around, through, or under the muscles used for your arms in order to move properly to fascilitate, well, movement.

You also need a wingspan in excess of 20 feet for an adult of average height and weight.

Bat wings present an extra baffling example considering they are LITERALLY arms, the ribs on the wings are basically fingers; with the spike at the top being its thumb. Why you wouldn't just give the guy wings for arms and get a far more unique looking character is straight up confusing.
