I have four sisters named Quart, but I am much larger than them all. I contain eight brothers named Pint, yet I fit inside a single plastic jug. I am the weight of eight pounds of water, but I am defined by the space I fill, not the weight I carry. What am I?

When I get scared, shake is what I do, particularly, in this type shoe.

Four quarts, eight pints, or six to eight medium-sized Reddit bananas. Imperial measurements are wild I tell ya

I am a breath of air inside a skin of stretchy hue, I dance upon the ceiling or drift away into the blue. I have no wings, yet I soar above the town, but once my breath begins to fail, I slowly tumble down.

I trim what grows upon your skin, and leave things smooth where hair has been. I work with care, both sharp and neat, but if I slip, I may draw some heat.
