1. Clara hasn't just done her homework.
- This sentence is incorrect. The use of "just" in this context is not appropriate because it implies that Clara has just finished her homework, but the use of "hasn't" indicates that she has not done it yet. The correct sentence should be "Clara hasn't done her homework yet."

2. They have lived here since 2006.
- This sentence is correct. The present perfect tense "have lived" is used to indicate an action that started in the past and continues up until the present. The use of "since" indicates the starting point of the action, which is 2006.

3. I have just saw a great film on TV.
- This sentence is incorrect. The correct past participle form of the verb "see" is "seen." Therefore, the correct sentence should be "I have just seen a great film on TV."

4. My English teacher has just missed the bus.
- This sentence is correct. The present perfect tense "has just missed" is used to indicate an action that happened very recently. The use of "just" indicates that the action happened a short time ago.

5. Have you ever gone to Italy?
- This sentence is correct. The use of "ever" in this context indicates that the speaker is asking about the person's entire life experience, whether they have had the opportunity to go to Italy at any point in their life.

6. Mum have already drunk her coffee.
- This sentence is incorrect. The subject "Mum" should be followed by the auxiliary verb "has" in order to make the present perfect tense. Therefore, the correct sentence should be "Mum has already drunk her coffee."

7. They haven't phoned me since yesterday.
- This sentence is correct. The present perfect tense "haven't phoned" is used to indicate that the action of not phoning the speaker started in the past (yesterday) and continues up until now.

8. I have known him since 5 years.
- This sentence is incorrect. When expressing a duration of time with the present perfect tense, we use "for" instead of "since." Therefore, the correct sentence should be "I have known him for 5 years."

9. My friend, Nicola has been to New York.
- This sentence is correct. The present perfect tense "has been" is used to indicate that the action of visiting New York happened at an unspecified time in the past with a result that is still relevant in the present.

10. The plane hasn't arrived already.
- This sentence is incorrect. The word "already" is not necessary in this sentence. We use the present perfect tense "hasn't arrived" to indicate that the action of the plane not arriving happened in the past and is still ongoing in the present.
