Are other solar systems the same in your universe?

We strongly suspect that every other solar system will be different, probably RADICALLY different, from our own. Every star is a little different; the mass that coalesced to form the solar system is different, and the unimaginably random factors that caused each solar system to form as it did - those are also different.

How are galaxies stars and solar systems are related to each other?

Galaxies are vast collections of stars, gas, dust, and dark matter, typically containing billions to trillions of stars. Stars form from clouds of gas and dust within galaxies, and they often have their own planetary systems, known as solar systems. Each solar system consists of a star and the celestial bodies that orbit it, including planets, moons, and asteroids. Thus, stars are the building blocks of solar systems, while multiple solar systems together make up a galaxy.
