(Are the expressions from 4 to 8 correct?)

Yes only #2 is correct and the expressions from 4 to 8 are correct.

Number 1 is also correct.

Michele is right about the others.

1. The correct sentence is "I will bring it to you." This sentence follows the correct structure of an object pronoun (it) followed by a preposition (to) before the recipient of the action (you).

2. Yes, the sentence "I will bring it for you." is correct. This sentence is also grammatically correct and conveys the same meaning as the previous sentence. Instead of using the preposition "to," it uses "for" to indicate that the action is done on behalf of the recipient.

3. The sentence "I will bring it you." is incorrect. It does not follow the proper structure of the verb "bring" when referring to an indirect object. To correctly convey this meaning, you should use either "bring it to you" or "bring you it," with the former being more common in English.

4. The expression "He looks like a mad man." is grammatically correct. It uses the verb "looks" to indicate his appearance and comparison "like" to express the similarity to a mad man.

5. The expression "That sounded like a lion." is grammatically correct. It uses the verb "sounded" to describe the auditory perception and the comparison "like" to imply the resemblance to a lion's sound.

6. The expression "He felt like a healthy man." is grammatically correct. It uses the verb "felt" to describe a physical or emotional sensation and the comparison "like" to indicate the similarity to a healthy man.

7. The expression "The fish smelled like a bad vegetable." is grammatically correct. It uses the verb "smelled" to describe a scent and the comparison "like" to imply the resemblance to a bad vegetable.

8. The expression "The bread tasted like soap." is grammatically correct. It uses the verb "tasted" to describe the flavor perception and the comparison "like" to indicate the similarity to soap.
