Few issues questions before starting website

Hi, we’ll soon lunch a website. I found a few issues and have a few questions about it:

1. http://solaristravel.rs/tours/kuca-akis-sarti/ – How to change “tours” in url link?

2. On the same page you can see white space between main image and gallery thumbnails. This is not on all pages. Can we remove this white space so that thumbnails can be just below main image? (like it’s normally by default in demo)

3. I want to upload another font. Where to upload it?

4. Where to upload and change favicon?

5. Is there option to add action bar above logo? Just to add there phone numbers and email.

6. When we are adding new product, why we don’t have there a visual composer? Is there option for that in future upgrades?

7. http://solaristravel.rs/tours/vila-estia-paralia-katerini/ – On second tab (beneath gallery thumbnails) you can see that table is going out the box. Is there possibility to automaticaly reduce the tables to be in box?

8. On single tour page, in tabs we want to add images which on click will open like popup. Like table pictures on bottom of this page – http://euforijatravel.rs/package/vila-pella-pefkohori-2017/
How to do that?

Best regards
