I agree that you Columbian Rock looks more like a Delaware.
And for your hens. They dont have a strong enough columbian pattern in my opinion to be pure Sussex and they are too light to be Reds and a little to dark and too much variation in the color shades to be buffs.

They are not Welsummers, their breast kinda have the salmon coloring but they dont have the rest of the Red Duckwing coloring of the Welsummers.

They look like New Hamshire Reds as I said earlier, NHRs have weaker black columbian ticking in their hackels and have a variation of differnt shades of the light gold color, and they have yellow legs.
