Answer:

3. I wish I could find my phone.
4. If only I had the money to buy those shoes.

Explanation:
Sentences with "wish" and "if only" express a desirable hypothetical situation. In other words, when you use them, you express what you would like reality to be like. For example:
- I ruined dinner because I cannot cook.
I wish I were a good cook.
If only I could cook well.
Notice that we use the simple past of verbs or the modal "could" in the sentences.
