Thanks stephen, I checked live test , it says, failed , 404 not found and removal request is accepted as well. Tried to gleen logs but it'll take some time for me to get used to of them, this was the first occasion for me to see how logs look like.

I've submitted a sitemap and urls are gone for now through same url removal request. Is it possible to make google crawl only pages from the sitemap. I've found that the last crawl date for these spam pages were before I moved to a new host. I hope that they don't reappear now. I've made a small edit to question as well.

when I click the search result, my site says: It seems we can’t find what you’re looking for. Perhaps searching can help. Just looked in inspect url , google says for http property: URL is not on Google, its unknown to google. For https property, its says url not in property, switch proerties or inspect url from current property.
