Questions about few effects

Hello, I have a few questions about effects that I don't fully understand how to do, attached is a gif and the actual questions.

1. The first is how to make the same effect as on the text.
2. The second is how to make the same smoke above or below the character.
3. Third, how to make the effect that appears near the hand, red elements.
4. Well and the fourth, the character holds a crystal in his fingers, which shimmers with light, how to make about the same glow or glow?

Thank you, thank you in advance for your answers, I'm still learning and want to perfect my work!
