You can cast a card for its miracle cost only as the miracle triggered ability resolves. If you don't want to cast it at that time (or you can't cast it, perhaps because there are no legal targets available), you won't be able to cast it later for the miracle cost.

Multiple card draws are always treated as a sequence of individual card draws. For example, if you haven't drawn any cards yet during a turn and cast a spell that instructs you to draw three cards, you'll draw them one at a time. Only the first card drawn this way may be revealed and cast using its miracle ability.
The tokens created by the squad ability aren't "cast," so any abilities that trigger when a spell is cast won't trigger for the copies.
