Repairing scratched kitchen tile

Hi,

We've got some damage to a couple of kitchen tiles. We didn't put the tiles in initially so not 100% sure on the material, but suspect vinyl / lino as it doesn't feel like real wood.

Photo attached.

What are our options? Is any form of repair possible?

 

It's ceramic tile, either pop the broken ones out if you have spares if not grout the cracks
