Minor Developments To Make In Website (Wordpress)

We want the following developments to get done in the website: 1) On our homepage, we have all the parent categories to be shown, but we want a system to replace few or all of them accordingly, whenever we want, with our selected sub categories or child categories. Please refer attachment. 2) In the category or sub category page, we have all the categories listed. We want to have only same level categories to be listed there. 3) Please add a disclaimer, i.e., "Disclaimer: Image and appearance of products are indicative. Grydle and Sync reserve the right to change appearance." on the product page, just below the Question and answer section as in the attached image. 4) For 15.6" screen system, our icons of "Add to Cart" box are being disturbed. Please make it as they are shown in 14" screen system, and also make sure they won't be disturbed for different screen sizes and resolutions. Also, please shift down the "Add to cart" box a little so that it can be aligned with the title of the product. Please refer image for all. 5) We have the provison of recommendation in the product page of the same child category products. But for different number of recommendations, their width and height is different, please make them of the same size and to the size of the recommendations of the three number of products. Please refer to attached image.
