Dear fellow Writers, I have a few writing questions?

2.  Most of my stories, I prefer to write from a narrator's perspective, but I don’t know how to give characters depth or an inside look at how they feel or mentally and emotionally react to something.

here is an example I think show good narration:

Hunter adjusts his seatbelt, gripping the steering wheel, trying to navigate through airport traffic.

He looks over to Savannah who is leaning her head against the wall, listening to the music playing on the radio softly in the background, trying to forget that her world has changed completely. 

He opens his mouth to talk to her, and say anything that can help, but nothing comes out. So instead, he tries to focus on getting home and preparing himself to talk with the detectives.

3.How do I move my characters of give them actions without it sounding like I am just giving the directions?

For examples, I feel like I write like this.

Sally and Mark are standing outside in the rain. They are arguing about why he has not asked her to be his date to prom. She pushes him to get away and turns to run away, He follows behind her to continue the conversation and grabs a hold of her hand. She looks at him, he looks at her. 

EX2:

Amy walked downstairs to the kitchen to get something to eat for breakfast. She goes to the cabinet to get a bowl, then walks to the pantry to get cereal. She then goes to the fridge to get milk, but there is none. Turning around she notices, her brother sitting at the the table, with an empty carton of milk next to him and a full bowl of cereal in front of him

I feel like it sounds like character A moves here and then character B does this and moves this way and Character A then looks at B like this and then B looks at A like that. 

If you can answer at least one question that would be of great help.
