1. Lighting from below is tough to make work and you almost did. A stronger ratio might have done it. Her hand is too prominent, especially with fingers spread apart. Hands are as big as heads so don't have them compete for attention.
2. Poor. Flat, unflattering lighting, no story.
3. Good. Needs PP, clean up stray hair, etc.
4. Good. Play with the crop, 4:5 is probably a better ratio. Too much background that doesn't add as negative space or content. She was relaxed and engaged and trusting, that makes the photo.
