Change styling to some elements

Hi,

I’m using a review form shortcode and a display reviews shortcode on my single product page, I want to make some changes the styling. Please see attached image and my 4 questions:

1. How do I style this ‘write your review’ shortcode button? I’d like to make it bigger and make changes to the border color, text color and background color (to match the filter buttons)

2. How do I style the filter buttons? border color, background color, text color?

3. This top number pagnation I do not want to show, since it already shows at the bottom. How do I disable/hide this top one?

4. How to change the styling of this review page number pagnation? I do not want any square background, just number and to make text size smaller

5. Is it possible to make this number pagnation look like this? and in the center? I could pay for custom work if not.
