4. Although she finished her works, she stayed at the office two.

Step-by-step explanation:
I have been able to show the error in each of the sentences and at the same time, I have made corrections to the errors.
We can see that in no. 1, the use of "me" isn't appropriate because "me" is an object pronoun. "I" is the best pronoun that fits in that sentence because it is a subject pronoun.
In no. 2, the use of "hardly" an adverb is not appropriate in the sentence. The correct word is "hard", an adjective to modify the noun "working". In no. 3, the article "A" is not appropriate in the sentence. The correct article to use is "The". It shows that the "specific" given to her by her boyf**end is expensive.
In no. 4, "works" and "two" are wrong. The correct words to use in the sentence are "work" and "too".
