You can get all users’ content, then set the index of the image you want to show at the moment, and in the setInterval hide all images with display: none except the target image with display: unset, and increase the index by one on each iteration, and when the index equal or more than the images length reset the index to zero.

const users = document.querySelectorAll(".user");
let index = 0;

const handleChange = () => {
    if (index >= users.length) {
        index = 0;
    }
    users.forEach((user) => (user.style.display = "none"));
    users[index].style.display = "unset";
    index++;
};
setInterval(handleChange, 4500);
handleChange()

Your interval is 3000 ms, while two of your timeouts are 3500 and 4500ms, respectively.

Your timeouts have to be shorter than the interval period.

setInterval(testimonial, 4500);

function testimonial(){
    setTimeout(() => {
        const box = document.getElementById('hellouser');
        const rain = document.getElementById('hellouser1');
        box.style.display = 'none';
        rain.style.display = 'block';
    }, 1500);
    setTimeout(() => {
        const rain = document.getElementById('hellouser1');
        const rainbow = document.getElementById('hellouser2');
        rain.style.display = 'none';
        rainbow.style.display = 'block';

You could take a slightly alternative approach and use CSS animations instead of JS.

This snippet has an animation time of 3 seconds. Each hellouser element is set to have opacity 1 for one third of the animation time. The second and third of these elements have their animation delayed by one and two seconds repsctively.
