This is what we would call a run-on sentence. It would flow better if you split it up
Ex: I study alone at home and I want to improve my English because I'm visiting my friend in 5 months. Therefore, I'm writing on this site, and I am working very hard.

My friend and I have notdo not speak the same language.

In English, we don't say that we "have" a language. This is just a rule we have.

He speaks English and Spanish and, whereas I speak Arabic, French and a bit of both English and Spanish.

Great job with this sentence. The only corrections I made were stylistic and just sound slightly better. Great job, though.

I fightwork day and night to improve it. I am so excited to meet my friend.

Fight sounds slightly weird in this context. I get what you're trying to say, but fight is more often used when talking about emotions or something physical.

I always review lessons and I repeat the words again. If I don't understand any word, I look it up in the online dictionary online.

Online dictionary sounds more natural here.
