Bottom plant viburnum nudum burning bush in middle and Viburnum top

Thank you for all your help and Happy New Year. My students took these photos and I am trying to help them with their identifications. I will post the only possible leaf photo which may be from the top plant.

The leaves in first photos are not clear enough to tell. I wonder if it could be buckthorn (Rhamnus)? Check out the included link for one of species in the genus, the R. cathartica images. Again I’m only speculating. https://www.invasive.org/browse/subthumb.cfm?sub=3070

Could you give us more photos of the top & bottom plants? For now, check out a species in the dogwood (Cornus) genus, the C. obiqua (narrowleaf/silky dogwood). Click on images to enlarge. Best wishes! https://florafinder.org/Species/Cornus_obliqua.php

Thank you. That would probably be the one in the middle. Any clue about the ones with the non-red leaves? Wondering if I was supposed to post different plants individually on your website.

perhaps Euonymus atropurpureus Eastern wahoo
