Yafi means "from the city of Jafa", which is a city in Palestine. You are probably referring to the poet and scholar Umar bin Muhammad al-Bakri al-Yafi, also known as Abul Wafaa, who came from the city of Jafa in Palestine. You can use Yafi as a name since it doesn't have a bad meaning.

As for Rashdan, you can see its details here: Rashdan

Since both Yafi and Rashdan have good meanings, you can use Yafi Rashdan as a name
