This looks to be the main Darajani market building, but it seems the market area goes all the way across creek road passed the school.
If that is is, can you draw an area and tag it:

amenity=marketplace
area=yes

And then create a multipoligon
type=site
name= Darajani Market
amenity=marketplace

And add the area + all the buildings that are market buildings to it.

This building and the one across the street have sections of 5 and 7 levels.
It is hard to see the cutoff point from imagery.

(its even on wikipedia:
https://en.wikipedia.org/wiki/Michenzani

)

Could you adjust the area for amenity=school? it is quite hard to see if the basketall pitch belongs to the school.

building=container is ment for sea=containers turned into (mostly) shops.
if these are containers, they need to be drawn seperately.
Could it be this is merely a roof with market stalls under it? If so
building=roof
amenity=marketplace
(see the other note about the market)

Is this the House of Abdu Uwahab (Green House)? If so, can you name it that way, and add
building:architecture:historic=yes
