Show 4 crowns on desktop, 3 on tablet and 2 on smartphone

Hi!
Please tell me how to make more than 3 columns. This is too few columns for my site. Is it possible to make an adaptation for different screen resolutions and for a smartphone 2 speakers, not 1.
How to make not 30 recent reviews in the grid, but your own number, for example, only 6-8?
Thank you very much.
