Welcome to the Q&A Forum

As much as I would love to answer all of your questions, they would require a lot of time to explain.  I will however comment on the website that you referenced getting links from huahinafterdark.com. I checked out the site, and the domain authority is not all that high, but what bothered me the most is that the page is full of links.  I always try to obtain content links from sites that are not full of links.

Since you stated that your site does not have that many links, I would probably not worry about disavowing them, but I would concentrate on getting better links moving forward.
