Is it possible to pause a youtube video without using the api, and if not, how can I insert a lot of players on the page using the api?

Question

YouTube

Hello everyone, I have the following problem -
there are a lot of sliders, they should contain photos and videos. Sliders are pop-ups that appear when you click on the preview and disappear when you click on the cross.
I inserted the video as an iframe, but the problem is that when the user tries to close the slider, the video continues to play. I tried to add vids via api, but as far as I understand, there will be only one player in this case, and many vids can only be added as a playlist.
How can such a problem be solved?
