Yesterday I read about the topic aboutof ' Algerian customs and tradistions.'.

You can "read about a topic", but you can't really "read a topic."

I wahad listeninged to it a bunch of times over and over.

"I was a listening..." works in oral conversation but the past perfect ("had (verbed)") sounds better in writing to explain what was happening in the past. Adding "over and over" emphasizes the sense of repetition.

I also understood the most of the words, But my big problems is that I can't use those words in thea sentence.

But every minute II suddenly changed my mind, and I decided to write thoses sentencepractice writing sentences that use those words.

"Every minute" I don't understand your meaning here, I think you mean "suddenly"? You could also say: "But at one point, I suddenly changed my mind..."

Those new word that I learned such new words as: diversity, contains, portion of, and mixture.

It's a little hard to explain, but the correction helps the sentence flow better

Algeria ishas a diversity of the dishes and it is theat differ tofrom town from anotherto town.

A place can "have diversity," but you cannot say "...is diversity." You can say something "is diverse"": "The cuisine in Algeria is diverse." "Algeria is a diverse place." "Algeria is a place with a diverse cooking culture."

Something "differs from place to place," you don't need to use "it" in this context but you could in a different one:
"I really enjoy trying different food in different regions of Algeria, the cuisine is so delicious and it differs from place to place."

In Inde contains of the religions and the differents culturedia is a place where different religions and cultures are contained in the same country.

You could also say: "India contains many different religions and cultures."

"Contain" should follow a place or space or idea, if you say "In (country) contains" it sounds strange grammatically.

In Algeria is, a portion of ethe population is European foreigners.

"portion of" typically needs to have "a/an" at the front of it. "A portion" also needs an "of“ after it, as it refers to a part of a larger whole.

In Algeria is contains a mixture of the differents cultures such as: Arabes, b and Berbers.

No need for "In (Algeria)". If you want to phrase it like that, you could say: "In Algeria, there is a mixture of different..."

Since you put "such as" after "cultures," you should say "Arab and Berber" instead of "Arabs and Berbers," because you wouldn't say "Arabs cultures" or "Berbers cultures."
