Brother, from all the questions you have asked thus far, how did it benefit you? What's your objective?
Would it not be of more benefit to work on our own spirituality than go on asking about these things?
Every Sahabi رضي الله عنه has a position in his own right. Each of their stories include lessons for us. Rather let's take the lessons from their lives.
That which we know regarding the rank of the four Khulafah and their status has been mentioned.
A Prophet will always have a higher status than a Sahabi.
In addition, the rank of the lowest ranking Sahabi رضي الله عنه will always be higher than that of any person who came after him-no matter how pious or great the person may be.
Also, we should not try and judge between the Sahaabah رضي الله عنهم , those decisions are not for us. Which ever one of them you follow you will be on the right path Insha Allah.
Let us keep in mind, it's necessary to learn. Knowledge can be attained by asking, but over-questioning can lead to destruction at times.
With peace
