As for the squash, if the flowers are male flowers, no, that's not where the squash will be. If the flowers are female, there will be a tiny, tiny squash at the bottom of the bloom, and yes, every single one will be a squash. You planted way too much, and should harvest them small. Around here, people start locking their cars, so they don't wind up with an anonymous bag of squash and zucchini in the back seat. ;)
On the peppers, I can't tell one from the other until it fruits. So good luck with that.

“You planted way too much,”
I only planted two plants but each one is a monster.
