Elliptical, Irregular, and Spiral
Irregular galaxies have no discernible shape.
Irregular ones!
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
They are ALL galaxies.
Irregular galaxies are believed to have been spiral or elliptical galaxies in the past, which have been distored through gravitational pull of neighboring galaxies.

There aren't really any other names for a galaxy that I can think of, but there are galaxy classifications, such as spiral galaxies (that can rotate either clockwise or counter-clockwise), elliptical galaxies, and irregular galaxies.
