I’ll be honest you’ll struggle to find where those tiles are from. How long has it been since the floor was laid?. The majority of tiles within a year from where you brought them from aren’t made or sold anymore as most stores have a limited number of metres they buy to sell. My suggestion is to either find a tile similar to it or replace all the tiles unfortunately. It’s hard to source tiles years down the line for repairs that’s why it’s best to save a box or a few spare tiles for future repairs.
