All are correct! Congrats on some difficult identifications!!
Thank you Writeacher!!
I disagree. #1 is not in the indicative mood. The word "when" and the question mark indicate a different choice.

Sorry. I learned this as mood. Verb mood is different from type of sentence. Girly girl will need to decide.

It seems there are differing definitions of what a "mood" is in English grammar. Some authorities say questions are in the indicative mood (there are only three moods). Others define more than three moods, including "inquisitive". https://en.oxforddictionaries.com/grammar/moods
