Hi Kempovic,
I hope you are well today and thank you for your question.
You can display slider on all pages using child theme solution shared in the following topic.
https://colorlibsupport.com/t/slider-on-every-pages/#post-47733
But to display different slider on every page you have to develop custom code.
Developing custom code for custom functionality is beyond the scope of support that we provide here.
If you are not a developer then you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. Colorlib recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5
