I want to know whether all the papers published in Scopus Indexed Journals will be in Scopus Database for sure, or scopus will evaluate all papers and take specific paper on their Database
Scopus filters at the journal-level for inclusion in the database, not at the article-level. So, if a journal is indexed in Scopus, the underlying articles will be indexed by default. Hope this helps!
