If you are checking the journals on SJR, FYI not all the Scopus Indexed journals are available on SJR the best way is to directly check them on Scopus Website under Sources Tab.
Which ever way some people came to the conclusion on whether any is Scopus indexed or not is a thing of serious concern.
All the above listed journals seem to be Scopus indexed on their websites and also have clearly stated why some of their works have not been noticed on the Scopus database.
In my opinion, if one is Scopus indexed, all are. If not, all are not.
Similar question was asked by Ojonimi Yusuf Usman in below link, all the three journals are Scopus indexed, and updated Scopus journals are available on www.scopus.com.
