Hello Ahmedstreets,

Welcome to OSM and thanks for your contributions. There are a few things you need to be aware of as you contribute to OSM. 

First, we use Title Case for names but not UPPER CASE. 
Secondly, the addr:street is reserved for the street the place is located. Not all streets in Ghana are properly named and signed so if there isn't one, don't make it up. Additionally, the street name should also be present in OSM. 
Lastly, the tag values should match the keys. For example, Adenta is a suburb of Accra, so the right address key for it is addr:suburb. addr:city doesn't fit because Adenta is not a city. 

Best,
Sam
