Can you explain the different Catholic Eastern Rites?

The Catholic has latin and eastern churches. What are they? Is the eastern catholic church the eastern orthodox or are they different? Is the latin church the western church?

Why is the catholic church divided into east and west?

Also, is Eastern Orthodox a catholic church?

I searched google and it said that latin catholic church as 23 independent churches and eastern catholic has 22 independent churches. i am afraid that protestants will use this to proved that catholic also has its division of churches.

Can you guys shed light on these churches?

Also, each catholic churches has different rites. How can we defend this?
