No, those do not look like wyandottes. Wyandottes should have a rose comb and only one of those looks like it might have one, and their legs are the wrong color.
Could be black Plymouth Rocks, but hard to say. Certainly not Wyandottes, other than maybe the one rose combed one. I think I see yellow legs on a couple of the single combed ones.
Now, some Wyandottes do have single combs pop out of their Cochin ancestry, but those don't seem to have Wyandotte body type.
