Anyone good at identifying wood types?

Is anyone good at identifying wood types? Because I'm not.

I got these rough-sawn boards (I love the look) from a post on Nextdoor. The lady said she was finished with a project and just wanted to get rid of all the leftovers (and there were a lot of leftovers - good for me!). She thought that they were exotic species, but wasn't sure what exactly. A commenter on the post guessed heart cypress, oak, and various pine boards.

Anyone have any other guesses? I know the lower shelf is pine, but I'm not sure about the back and the upper shelves. I'm including pictures after sanding and then after I applied 2 coats of Tung oil.

Thanks!
