The latter two resemble acorn squash's shape, but we cannot say for sure what they are. Hybrid crosses can occur among squash (pollen transfer among plants in your own garden or even from another person's garden that bees have visited). Further, even seeds from store-purchased squashes can sometimes germinate in compost. Volunteer squashes (all members of the cucurbit family) are edible. It may be "pot-luck" as to their flavor, texture, and overall eating quality.

Thanks Christa! I’m relieved to hear they will be edible.  I just hope none of the many critters get to sample them before we do.

You're welcome.
