1 Nuestros

2 Su

3 Sus

4 Mi

5 tu

Explanation:

SO the first sentence says that my brother and I arrived to the house of parents, so it would have to be Nuestros, since that is our, then the secon is Monica necesita --- backpack, so the option would be SU or her, the third one is RAmon searches for notebooks, and the option is His or "sus" remember that in spanish Su is his or her for a singular thing, and sus is her or his for plural, I call over the phon to friend, the correct option would me my-mi, and the last one is You go back to apartment, the correct option would be your-tu, remember that the difference between you and your in spanish is the accent mark, Tú is you, tu is your.
