Last photo – flowers details are too blurry to be certain. Maybe a cultivar in the oakleaf hydrangea (Hydrangea quercifolia). Click on the images to enlarge from the included link below. https://en.wikipedia.org/wiki/Hydrangea_quercifolia

Middle photo – It’s hard to tell with our more details (flowers, fruits & the main trunk.) I’m guessing a type of oaks (Quercus) perhaps? If this is an oak, its acorns are needed to narrow down. For now check out the red oak (Quercus rubra). http://www.namethatplant.net/plantdetail.shtml?plant=1198

Top photo – Plant with white flowers, a cultivar in the Deutzia genus. Check out the D. scabra ‘Flore Pleno’ from the included link below. Click on the images to enlarge. Best wishes! https://landscapeplants.oregonstate.edu/plants/deutzia-scabra-flore-pleno
