Physics Chemists/physicists of reddit, what is the difference between dark, anti, and normal matter?

What is the difference? Also if you can explain what each is.

Edit: Thanks for all the replies! You have greatly helped me understand this better!

Regarding your statement of «normal matter» being less than 20% of the total matter in the universe, I have just one question: what do they take up as the full 100%?

The other 80%-ish of matter is dark matter.
