I have already graduated from the university, but lastly ı. I thought ıI knew English very well, but it wasI do not.

Use of the definitive article "the" is not correct here, because it attempts to refer to a specific university even though you did not previously specify from which university you graduated. Here, you are referring to a university as a general concept. In these cases, the definitive article "the" must be removed.

I have just learned anything related to the curriculum, so now I have just specified two hours in my day to learn English.

It is not clear to a native English speaker what you mean by this due to grammatical errors and ambiguous phrasing. Are you referring to your curriculum at university, or your attempts to learn English after you graduated from university?

In addition, I want to use all the words that I have learned before, but ı do not know how I can ı put them ın my essay or ın my writing learn how I can write sentences in English with all the words that I have learned before.

Remember not to place any spaces between a word and a full stop (also called a "period"). For example:

Correct – "This is a correct example."
Incorrect – "This is an incorrect example ."

So from now on ı will write every day a small paragraph, and I will be happy ıf you correct that for me

So from now on, I will write a small paragraph every day. I will be happy to receive any feedback or corrections.

I want to learn English deeply.

I really want to learn English deeply.

I have already graduated from the university, but last. Lately ıI thought ıI knew English very well, but it was noI don't.

You could also say "college" instead of "university".

I want to learn English deeplyvery well.

"deeply" feels a little odd to me for some reason.

I have already graduated from the university, but lastly ıand I thought ıI knew English very well, but it was noI didn't.

"but it was not" is what you would say to contradict a "[object] is/was ____" statement. Like, "I thought my class was at 5 PM, but it was not." But this is an action that doesn't use "is" or "was", so using "but it was not" sounds very bizarre here. I would say something like "but [subject] didn't/doesn't/don't". "I thought she always went to the store on Monday, but she doesn't apparently."

I have just've only learned aneverything related to the curriculum, so now I ha've just specifidedicated two hours in mevery day to learn English.

"specified" is a very odd and extremely fancy word that not a lot of people will understand. I'm pretty sure you mean "dedicated".

In addition, I want to use all the words that I have learned before, but ıI do not know how I can ı put them ıin my essay or ıin my writing .

So from now on ıI will write every day a small paragraph every day, and I willould be happy ıif you could correct thait for me

First part isn't wrong, but "every day" is more commonly found at the end of the clause or at its beginning (but after any conjunctions like "so").
For the second part, although future tense works, you can also use past tense verbs like "would" and "could" to talk about a theoretical situation instead.
