Description says there are multiple sizes in each box??

The description is wrong -- there is only ONE size included per box/etc. However, each single size can be used for a wider range of different wire size combinations than can traditional-style single-color wire nuts.

I want to wire replacement turn signals on my motorcycle, I dont see how these really work? Anybody clue me in?

Hello! Those wire nuts are intended for residential and comercial wiring, and NOT FOR automotive (cars, motorcycle, etc) use!, in that case you need to use crimp tubes or welding the wires and after that apply shrink tubes. Other wise yoy will experiment troubles. I hope that this information helps you. Best Regards, J. P.

Do these have a round wire spring or square wire spring? I'm joining #10 solid to #10 stranded and am concerned about damaging the stranded.

Same rules apply though; lead stranded slightly....it makes sure the stranded is pinched at the lead point of solid, stays tight to solid shaft so less abrasion to stranded
