The study from the first screen shot is studying districts/zones along the border areas between Afar and Tigray, emphasizing the lowland agro-ecology. They don't really specify the ethnic makeup of the area.
I'm going to make the assumption that these are Afar camel herders living along that "border". A different article mentions Afar and Tigray sharing grazing lands, with Afar heading uplands during certain periods.
What I've said so far also applies to the article in the 2nd screenshot you shared. They're studying the east areas of North Wollo bordering the Afar region. Again, they don't specify ethnic makeup. So I'm again making the assumption, given the small number of camels compared to other livestock, those more than likely are on the border areas belonging to the Afar.
And that third screen shot, Hidareb are Beja and Tigre are semitcised Beja from what I've heard. So it makes sense they are mostly a pastoral people compared to Tigray and Amhara. So camel usage and consumption amongst them is not surprising. However, they exist in Northwestern HOA, completely irrelevant to the areas east of the highlands that we are discussing.
With that being said, Camels making their way into the Highlands from the east, would be from a lowland east cushitic group such as Afar and Somali. Even if Ethio-Semites adopted an affinity for camel, it would have resulted from that contact as the alchemist was saying. But it still looks like Habesha muslims do not have any affinity towards camel, as shared from the last screenshot of idilinaa's previous post. The argobba despite be very near camel pastoralists, do not consume camel nor have they adopted a camel herding lifestyle.
