Elliptical galaxies have an abundance of low mass stars or red dwarfs.
Spiral galaxies tend to have blue colors due to the presence of young, hot stars that emit blue light. Elliptical galaxies, on the other hand, are typically redder in color because they contain older stars that emit more red light. This color contrast is a result of the different star formation histories and compositions of the two types of galaxies.
Elliptical galaxies are generally round or oval in shape, lacking the distinctive spiral arms seen in spiral galaxies. They typically have a smooth and featureless appearance, with older star populations and little ongoing star formation. Elliptical galaxies also tend to be more massive and contain mainly older stars.
Because of their age, elliptical galaxies are believed to have older stars and less gas and dust in their insterstellar medium than other types of galaxies, and thus their nebulae are less common. However, nebulae are presumed to exist in almost all galaxies; and some recent observations hint that the central black holes of elliptical galaxies may tend to preserve interstellar gas by preventing it from cooling enough for star formation.
There are generally three types of galaxies: spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies like the Milky Way have a disk shape with arms of stars spiraling out from a central core. Elliptical galaxies are shaped like ellipses and contain mostly older stars. Irregular galaxies have a less defined shape and tend to have a mix of young and old stars.
Very lens-shaped elliptical galaxies have a high amount of reddish stars. Hence both their shape (the "spiral arms" have pulled inward over time) and the color of the stars implies they are very old galaxies. Spherical galaxies - I'm not up enough on that topic, so I will leave that part of the answer to another.

You can have dwarf elliptical galaxies.
No. Elliptical galaxies are some of the oldest galaxies.They are also called early galaxies. The elliptical galaxies are made of low massed stars, a sparse interstellar medium and very low star forming characteristics.

Elliptical galaxies have a red color because the stars in them are older and cooler. An example of an elliptical galaxy is Maffei 1.
I think elliptical galaxies are the galaxies you are referring to. Scientist normally describe them as a flatted disk shape. These galaxies contain mainly older stars.
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
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.
Elliptical galaxies are generally round or oval in shape, lacking the distinctive spiral arms seen in spiral galaxies. They typically have a smooth and featureless appearance, with older star populations and little ongoing star formation. Elliptical galaxies also tend to be more massive and contain mainly older stars.
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
Elliptical galaxies are generally old but not very bright
