Shh! Can you hear that? Pay attention and be quiet

First: symbolises your nation. Second: is found north and south. Combined we stand proud, holding First in jubilation.

I guard your toes from mud and rain, March through puddles without complaint. On farms I rule, in armies too, Sometimes I’m kicked when dreams fall through. What am I?

If you like apples, you can do this with friends. But if you're in prison, you'll have to do it yourself.

I hold your steps together each day, or speak of budgets stretched to fray. Pulled through holes, I twist and brace what am I you tie in place?
