I want to adjust the styles of my slideshow that are not available within squarespace

I would like to adjust the styles of my slideshow sections that don't seem to be available within squarespace itself. 

I am wondering if anyone with css/ html/ javascript experience can help me? I have attached 4 different images of 4 different slideshow styles I want to recreate. Can anyone help me?  

Thanks, 

Summer

First is possible with Summary Block (use CSS code to style arrows style)

I think second with List Carousel + CSS

Third, there is a plugin

Final, change both image + text or change right text only?
