The first is right, but the next two are upside-down
Not that I can read Amharic, mind you, but I lived in Ethiopia for a year, so at least I know how it looks (sort of). It might actually be in Ge'ez and not Amharic. Ge'ez is the liturgical language of the Ethiopian Orthodox church, and seems to be used on swords sometimes. I asked an Ethiopian acquaintance if they could translate a sword inscription and it turned out to be Ge'ez. It uses the same alphabet but is a very different language -- sort of like Latin is to English.
So, you may need a priest for that one.
