Lavender looks right, not sure about breed. You should post some better close up photos of "head on" and profile, top of bird to see if there are any saddle feathers. Also only see one bird in your photo. Age?
Oh and welcome to the forum!
They look female so far. They are lavender (self blue) and very pretty, but do not look like orpingtons, look more like ameraucanas. Orpingtons have full, round bodies. If so, you will not know for sure about gender until they are around 12 weeks old.
Orpingtons have single combs, these birds look like have pea combs.
