Is the nucleus found in all cells?

No.

Every living cell of animals, plants, and other eukaryotes contain a single nucleus -- that, in turn, contains the DNA.

However, about a quarter of the human cells in the human body are red blood cells, which do not contain a nucleus or DNA.

Also, the cells of bacteria and other prokaryotes contain DNA, but do not have a nucleus.

(Here "nucleus" implies "biological nucleus", a single organelle inside the cell that contains the DNA. Atomic physicists use the word "nucleus" differently, the clump of protons and neutrons at the center of each atom. Every cell contains water, DNA, and other molecules; the molecules are composed of atoms which each have an atomic nucleus, so there are typically trillions of atoms and therefore trillions of atomic nuclei in each cell).

In general, yes every cell has (or had) a nucleus. There are some extremely rare exceptions such as the red blood cell of mammals, which has a nucleus as it develops but at maturity ejects the nucleus. Because the red blood cell discards its nucleus, it becomes unable to repair damage to itself and has a very limited functional lifespan.

A nucleus can be found in all vertebrate cells, withe the exception of the red blood cells of humans and Batrachosepssalamanders.

No, Only eukaryotic cells have a nucleus. Prokariotes (i.e. bacteria) have no nucleus. The red blood cells of vertebrates also lake a nucleus.
