I believe the one with definite chipmunk markings is definitely a partridge as guessed.
The more grey-ish looking partridge will most likely either be a silver partridge or a gold partridge when older. I’ve never have silver partridges myself but I have hatched gold partridges that were a similar colour to that at that age.
The last one in the photos looks like it’s the typical yellow of a white Silkie. Since it has black spots, possibly a paint. It can be really hard to judge though as the photo may not be showing it’s true colours well. If it’s super orange in colour in person, it’s most likely a impure gold (just a gold with extra black on the wings and tail feathers).
They are all super pretty! I will say post them back here in a few weeks time once their feathers are coming in and the colour should come through then, particularly in the last chick.
Here’s some of the partridges I’ve hatched, all varied in chick down colour:
