are these sentences right?

Hi there,

I wonder if someone can help me with the following sentences. I'm not sure if they are grammatically correct as well as if they make sense.
Thanks!!!

After seeing the video, we commented all things about it
Some guys knew already what the book was about / some guys already knew what the book was about (?)
These compositions are very well written up

The teacher proposed us to do a composition about Anne Frank’s hidden stay
I think that everyone has put all efforts on it
The book chapters have easy vocabulary that helps to read them fastly

Oliver Twist learned to rob and to be as sly as a fox/ like a fox (?)
Oliver Twist passed a lot of adventures and he passed very good moments.
