How to add a video page to my site…

I need someone to help me update the Video page for my site… im trying to add a better looking page then i currently have. here’s my current video page https://imaroachkilla.com/bossinasstv but i wanna update and improve it. I don’t like how it shows one big video and there all on one page. instead of having a ‘preview’ page with 3-5 vids per line and once U click it it’ll take u to the video. Hope that isn’t confusing. Can anyone help or point me to the right direction on how to improve this situation.
