There is no planet Kepler. Designations such as Kepler-69c are given to planets discovered by the Kepler spacecraft. This spacecraft has discovered planets ranging from 100 to 7,000 light years away.
Johannes Kepler discovered that planets orbit the Sun in ellipses with varying eccentricities in the early 17th century. This became known as Kepler's first law of planetary motion and revolutionized our understanding of planetary orbits.
Ceres and Eris are not planets; they are classified as dwarf planets. Eris was discovered in our solar system recently and not by the Kepler mission. Ceres is not "new" either; it was discovered the first day of the 19th. Century. I didn't check the specific "Kepler-" codes, but that looks like planets discovered by the Kepler mission to be orbiting around other stars.
No, Johannes Kepler is best known for describing the laws that dictate how orbits work. The Kepler planets were discovered by the Kepler telescope, a spacecraft named in his honor.

There is no planet named Kepler. Kepler is the name of a space telescope used to find planets in other solar systems. Planets discovered with this method are given designations such as Kepler 22-b. Some planets discovered have been larger than Jupiter.
Kepler discovered that the planets orbit the Sun in elliptical shapes, not in perfect circles as previously believed. This finding is summarized in Kepler's first law of planetary motion.
There is no single planet named Kepler; rather Kepler is a prefix added to the designations of planets discovered by the Kepler telescope. Several planets discovered by Kepler, including Kepler-438b, Kepler-442b, Kepler 440b, and Kepler 296f, orbit in the habitable zones of their stars, which means they might have liquid water on their surfaces. Currently we do not have the technology to determine if they actually have liquid water.
The new planets are named after the Kepler Space Telescope, which was a NASA mission that searched for exoplanets using the transit method. The telescope discovered thousands of exoplanets during its mission.
There is no single planet named Kepler. Rather, the Kepler label is added to the designations of planets discovered using the Kepler telescope. Planets discovered in this way are given designations such as Kepler-20f and Kepler-87c. There are more than 1,000 of these planets that come in a wide range of masses and a wide range of surface gravities.
