In Search of Abraham's Ten Tests

Let's return to Avot 5:4 (see earlier blogposts here and here), which teaches that Abraham was set ten tests by God and passed them all, to demonstrate the strength of Abraham's love of God. 

Since the Mishnah does not spell out which are Abraham's ten tests, I have been trying to compile a list of them. The table below features 28 "possibles", of which no fewer than 19 are counted as one of the ten tests by at least one reputable Torah scholar.

Number	Test	Source (Torah or Midrash	Endorsement
1	Exile from family and homeland	Torah	Rambam, Rashi, Rabbenu Yonah, Bartenura, Me’am Lo’ez, Abarbanel

Can anyone add to this list, either by supplying more possible tests drawn from the Torah or midrash, or by supplying the names of rabbis who have endorsed any of the tests in the table above which have not (yet) to my knowledge been counted among the ten?
