Answer 1

try
<button id="<?= $fila['id'];?> " class="popup-btn">Click Me</button>
jquery
$('.popup-btn').on('click', function(e){
e.preventDefault()
let id = $(this).attr('id')
//do magic
})

Answer 2

Using vanilla Javascript you might try like this. Remove the ID attributes or convert to dataset versions such as data-id="popup-wrapper" rather than id="popup-wrapper" and use the click event triggered by the button to locate that element in the DOM tree. From that point you can navigate up the DOM tree and query once more to find the POPUP. Once you have identified the popup - open it or do something.. here I just toggle a className.
All the PHP tags below have been removed simply to facilitate the snippet/demo...
const clickhandler=function(e){
let popup=this.parentNode.parentNode.querySelector('[data-id="popup-wrapper"]');
popup.classList.toggle('popped');
/* Open the popup... sing and dance! */
};
document.querySelectorAll('.popup-flex > [data-id="popup-btn"]').forEach( bttn=>bttn.addEventListener('click',clickhandler))
.popped{border:2px solid red;}
td{border:1px solid grey}
