Hello Abdu Jalil,
Welcome to OpenStreetMap and thanks to contributing to the map in Ghana. As a new mapper you have a couple of mistakes in your changes but I have reviewed and corrected the ones I can.

Kindly pay attention to existing amenities/places before you add them. You added new nodes for places that already exist.

Also take note of the tags you use. Do not use tags if you don't completely understand them.

You are invited to join the Ghanaian community on Telegram to learn more about contributing to OSM: https://t.me/osmghana

Sam
