I attach an image with the solutions to your question made by me, I leave the explanation below

Depending on who the verb falls to, it can be one or another reflexive pronoun.
They are classified as follows:
- "To me" ⇝ "me"
- "To you" ⇝ "te"
- "To he/she" ⇝ "le"
- "To we" ⇝ "nos"
- "To you" ⇝ "os"
- "To they" ⇝ "les"
In this case, we can analyze the model of the exercise to clarify the other sentences.
- A mí me gustan los conciertos.
"A mí" is a direct object (DO), since it is the preposition "a" and an animate being.
"Me gustan" is the verbal nucleus of the verb phrase of the sentence, it is a reflexive verb.
"Los conciertos" is the subject of the sentence.
Note: These types of sentences are very common to see them with this construction: Direct object + Verb + Subject (DO + V + S).
