1) I wouldn't bother with the dailies until you can complete the H missions, the drop rate is just too low. IIRC Pastoral Gate is the mission that gives the most unit XP/charisma early on.

2) If you're a free player i suggest saving your SC for things that are harder to get than affection items; you can farm them anytime from challenge quests. Even if you're paying there's better thing to spend them on.

3) In addition, to what Ericridge said, I don't see either Katie or Cloris on your team. Get them, level them.

Don't panic yet; you still have a bit over a week to get Noel.
If near the end of the next week you're still just barely short of completing maps 4/5 and you're willing to spend the SC, consider buying shrine boosts to give you enough of an advantage to 1* the maps.

Also check out the stickied threads, there are a few tips for newbies there.
