Maran or ? 7 weeks old and just not sure.

#1 and #2 look like Barred Rocks, since they have single combs.

Agreed. They also seem to have yellow legs, which means they're probably not Cuckoo Marans (which have white legs).

Then what is the white bird ? I got 3 from the girl breeding marans and the white one was in that batch

It was not a hatchery bird she had 4 h birds etc
