If you Click on the first shape you want to adjust, then use Shift-Click to select each shape you want to adjust as a collection, any changes you make one will apply to all of them. Unless they're on different pages, though, you wouldn't want to give them all the same horizontal and vertical positions; otherwise they'd all end up one on top of the other - either position might be OK, though.

PS: This technique does not apply to inlineshapes.
