Need help.

1. I have a problem with the slider on the homepage, I need to adapt the 3 slideshow images that appear on the desktop and on the phone. Now they appear cropped portrait style on the phone. (check link in private content).
2. The three images on slider should run at 3 second intervals. Now they run at 10 seconds.
3. How can I set all images in woocommerce to be the same size? (check link in private content).
4. The Newsletter pop up box should appear one minute after accessing the site. If 5 hours later I go back to the site to pop up again. Same the next day or another time. NOT to appear except to those who have subscribed.
5. For products, I would like to highlight what is in stock and what is out of stock. At the moment, if you’re inside a product, you can’t know if the size you’re interested in is available unless you click on it. Can’t we mark the missing size with a color? This would be desirable not only inside the product but also in the product list on the category page where they all appear.

Thanks.
