The correct answers are I wish my magic wand worked properly!, I wish I were sleeping in my comfortable tower right now., and I wish I didn't have to turn these frogs back into princes.

When we wish for things to be different in the present, we use "wish" followed by a past tense verb (past simple or past continuous). "Worked" and "didn't have to" are correct past simple forms. "Were sleeping" correctly uses the past subjunctive continuous form to imagine a different action happening right at this exact moment. Using present tense verbs after "wish" (like "works" or "am sleeping") is incorrect.
