Kepler's theory eventually replaced Copernicus's theory after Tycho Brahe's measurements enabled Kepler to realise that the planets move in elliptical orbits and not in the circles and epicycles of the older Ptolemaic and Copernican models. Copernicus was able to simplify the older model by placing the Sun at the centre instead of the Earth. Kepler in his new theory of 1609 retained Copernicus's idea of placing the Sun at the centre.
Galileo did not have his own theory. He was a supporter of Copernicus's heliocentric theory and an opponent of the geocentric Ptolemaic theory. Eventually both theories were rejected in favour of Kepler's theory. But Kepler's theory uses the heliocentric idea from Copernicus's theory.

Copernicus developed an interim theory of the planets in which the Sun was at the centre instead of the Earth as had previously been believed. Although Copernicus's theory only lasted from 1543 to 1609 when Kepler's theory replaced it, it is regarded as a useful step along the way.
Johannes Kepler found out that planets move in ellipses and move at variable speeds as they travel round the sun. The former theory of Copernicus was not wrong, but Kepler's theory was found to be more accurate when accurate observational methods were developed. Later Kepler's theory was backed up by theory when Newton's law of gravitation came along. However in the 20th century Einstein's theory of relativity produced some small corrections to the Kepler/Newton theory.
Kepler completely replaced Copernicus's theory of the orbits of the planets, which was based on circles an epicycles, with a new theory using elliptical orbits. However Kepler retained Copernicus's idea of placing the Sun at the centre.

The discovery did not support Copernicus's theory directly but it raised doubts about the ancient theory of Ptolemy that said that all objects in the sky are in orbit round the Earth. Galileo was an aggressive supporter of Copernicus's theory but eventually it was Kepler's theory that became accepted and is still used today. Both Copernicus and Kepler placed the Sun at the centre but Kepler's elliptical orbits are supported by the later theory of dynamics.

Kepler formulated laws of planetary motion, while Copernicus merely(!) proposed that the sun was the center of the solar system rather than the earth.
The only part of Copernicus's theory that Kepler retained was the idea that the Sun is at the centre of the Solar System.

Nothing. Copernicus died years before Kepler was born.
Copernicus's theory did not fail but it was not as accurate as the Kepler model because it did not include elliptical orbits for the planets, as Kepler's model did. However the data for calculating the elliptical orbits did not become available until well after Copernicus's death so he had no chance of knowing about this change. Copernicus's model which used circles and epicycles was accurate to the standard of the observations that were available to him.
