A wall implies that there is something beyond the wall. So no.

Does a doughnut have walls or boundries � If by the big bang universe, yes, there are boundries expanding ever outward, but not walls. If by the cosmos, then probably no because what encapsulates the boundries and the universe? A house may have walls but there is always the world outside of it.

It has no boundary wall, but the background radiation left over from the big bang is probably it's outer limits.

The Universe is a phenomenal Black hole.
Light radiated from the stars of the Galaxies ,does not escape the Universe because it is restrained into a finite containment. A containment by definition has boundary.
Therefore it must have a supernatural WALL.

No, space is curved in a way that if you travelled in one direction long enough, you would return to your starting place from the opposite direction. This may seem impossible, but space is curved in the 4th dimension like the two-dimensional surface of a balloon is curved in the 3rd dimension. So if you draw a "straight" line on the surface of a balloon, it will arrive in the starting place from the opposite direction in the same way (minus one dimension).
The 4th dimension being "time" makes it even harder to imagine but the balloon example still demonstrates the basic concept.

The universe is surrounded by nothing.
To determine where the nothing starts there is a cosmic interface that recedes as it expands.
Even a nothing must be separated by something!

Imaginary boundaries are there but not a wall as such.

No, it doesn't. But that does not mean it is infinite either. After all, there is no cliff at the edge of the Earth, but there is not infinite surface area either.

no one knows we have never seen the edge of the universe.
