I want to talk about this mistake at the beginning. Here are some sentences that are correct:
Every nation is different, and each has various achievements.
All nations are different, and they have various achievements.

This sentence is incorrect:
Every nations is different.

This is incorrect:
They has various achievement.

This is correct:
Every nation is different. All nations have various achievements.
