It’s fine to have the same URL included in multiple sitemap files. The only caveat is ensuring that there is no conflicting information being provided across the different sitemaps. For example, having a URL in a ‘regular’ sitemap and an hreflang-specific sitemap (for different language versions of your site) is perfectly acceptable, as long as any hreflang annotations given to that page are consistent across both sitemaps.
