Symbol within a slide/slider and 3 Slides per Screen


I’m trying to create a slider that shows only 3 reviews at a time, with the 3 boxes centered between the left/right arrows. I can’t seem to align the testimonial symbols properly within the slide itself and just show 3 slides/reviews at a time. How do I do that?

Thanks so much in advance!
