Yes, we can see stars in other galaxies from Earth. In fact, some of the stars that we can see with our naked eyes on a clear night belong to galaxies other than our own. For example, the Andromeda Galaxy, which is the closest major galaxy to our own, contains billions of stars, many of which can be seen individually with binoculars or a small telescope.
However, it is important to note that the stars that we can see from Earth in other galaxies are only the brightest and most massive stars. The vast majority of stars in other galaxies are too faint to be seen individually from Earth.
