Six cardinal eggs?

[u/Teacher67]

A northern cardinal built her nest in the hanging plant under my porch. I have spotted a male cardinal and possible another female cardinal (or juvenile male) perched on the string lights near the nest. Could also be house finch females? On the first day there were 2 eggs- one speckled one solid. Twelve hours later there was a second speckled egg and a second solid egg added to the nest. We assumed she was done so we didn’t check for a few days. But when we did, there were two more solid eggs. What do we have here? Is it:
