Is it possible? How? And what does it mean for the settlers?
Very unlikely. Much farther, and very little around there to make a living out in that era. The whole attempt would cost a lot more, probably meaning much less settlers.
It might not even really last.
On the plus side, I gather that disease would hit a lesser number of settlers.
There are not many places in coastal Namibia where you can have a really working settler colony, the area is remarkably dry and its northern part is especially desertic. If it works, however, I imagine any sort of odd things happening if and when Afrikaner Trekkers and Liberian settlers meet.
You can see a much earlier involvement of the US in southern Africa, with possible global consequences.
what about in southern Angola before the Portuguese take it?
or could the US be able to do it in east Africa? such as Tanzania or Kenya?
East Africa if even further removed, and under Zanzibari/Omanite suzerainty. I really don't see the point, neither political or economical. Southern Angola is relatively easier, though it would interfere with nearby Portuguese activities (and the Portuguese and Brazilians were still into sthe whole slavery thing big time). Portugal may not be happy to see a colony of freed slaved supported by a foreign power near their own slave-trade bases. However I'm not expert about Angola in this timeframe, so I think it's possible.
The OTL location of Liberia and its thereabouts, anyway, made so much more sense on so many levels.
well i figured that East Africa would be way too far from the US for them to be able to control them very well.
If you want a better climate for settlers, at not just *too* much further a distance than OTL Liberia, somewhere in coastal Mauritania might make sense. I would suggest Senegal, but that's a tad too close to the French area of influence for an independent nation to thrive I'd think.
Part of Liberia's problems to start with was the fact that so many settlers died of tropical diseases within months of arriving at the colony. Get a healthier climate, and you'll possibly get a bigger, more robust population of Americo-Liberians.
Mauritania is even closer than Liberia, making it seem like a good possibility. What issues are there for Mauritania?
whats the best place with both habitable & arable land
Didn't this happen in Decades of Darkness.
EDIT: as for alt-locations of Liberia further east than OTL, the largely unclaimed area between the mouths of the Niger and Congo rivers seems more likely to me.
Hahaha you mean the tropical hellhole that makes other tropical hellholes look like the Italian riviera in comparison. They'd be dead within weeks.
Look at this population density map:

The bit between the Niger Delta and the Congo is sparse and 'unclaimed' compared to the west african coast for some very good fucking reasons.
The only halfway livable bit is northern Cameroon coast but that is hampered by the ruggedness of the terrain and the lack of reasonable harbours.
Someplace in west africa and getting the portuguese to part with angola are really the only options.
