Thanks, backlink came from below sample links, there are total 62 links received one site for example. My worry is google would consider as spam since there are many links. Good to have such backlinks or this would harm my site?
If the site has legitimate content and the links are legitimate, then you're fine. Google will most likely just ignore the links if they're spammy or of low quality. Especially if you have a reasonable number of quality links from reputable sites.
