For records prior to April 1, 1944 "Today, exclusion files exist only for cases appealed to INS headquarters in Washington, DC. There is usually no surviving record for non-appealed exclusion hearings, which made up the majority of cases."
That web page goes on to describe the subject index for the case files, searchable online on ancestry.com or via microfilms held by the US National Archives and Records Administration (NARA).
Each of the three examples you have seem to be people who were admitted to the US within a day or so of the ship's arrival. That isn't enough time for their entry to have been denied and then appealed to Washington, so it seems very likely that none of their special inquiry records survive. (The image you included for Jankel Samolisa is the record of detained aliens, not the page listing actions of the board of special inquiry. But it says he was given only one meal, so I presume Jankel was held for less than a day.)
In my own research I came across a family who was held for quite a number of days. I made a request to NARA by email, specifying the names, date of arrival, ship's name, etc. NARA replied to me that the file was available, and an estimated number of pages and the charge per page (I believe it was 80 cents per page). The reply included a link to a web site where I could authorize payment (I paid via credit card). Within a fairly short period of time (maybe two weeks) I got another email saying the scanned records were available for me to download. I got several dozen pages of records, including copies of the typed minutes of the board of special iniquiry, then another board of special inquiry when a relative already in the US came to be questioned, as well as a report from an inspector sent by the government to verify the relative's claims about his economic situation, and copies of bonds signed by other relatives promising to pay the government $500 if one of the immigrants ended up on public assistance.
