spiral, elliptical, and irregular. The only differences are shape. Elliptical galaxies are shaped like an ellipse, spiral galaxies like a spiral or pinwheel, and irregular don't have a uniform shape
See related for the differences.
Spiral,elliptical,and irregular galaxies
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
the two types of galaxies that are barred and normal would be irregular as my best guess
the types of galaxies are barred, irreagular, spiral, and a shape like an hourglass.
Yes. There are two types of spiral galaxies: "S" (normal spiral) and the less common "SB" (barred spiral, with an elongated center).
are spiral galaxies are generally older than elliptical
Any "order" would be arbitrary. The main types are spiral galaxies, elliptical galaxies, and irregular galaxies. Several variations exist, too.
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.

Astronomers can get all the morphological types of 100 billion galaxies in the universe by help of the merger rate.
There are three main types of galaxies: spiral galaxies (like the Milky Way), elliptical galaxies (oval or spherical in shape), and irregular galaxies (lacking a distinct shape). These classifications are based on the galaxies' shapes and structures.
