1. Kind of looks like loropetalum but I'm not sure it is hardy in zone 5.

2. Picture is too far away from the plant.

3. Looks like some kind of Dogwood (Cornus species)

Thanks! For number 1., it's probably not loropetalum because it doesn't have those kind of flowers. Earlier this year, it had bunches of small white flowers. Here is a close up of what's left behind of the flowers:

For number two, here they are close up they also had white flowers

1. looks like a Euonymus. Can't be Lorpetalum because it has opposite leaves.

2. I have never seen Japanese Tree Lilac in the flesh but I wondering if that is what you have. Are the flowers going over now? Were they denser and whiter before? I cant see if the leaves are alternate or opposite.

Regarding number 2 the leaves are opposite. The flowers were much denser and whiter. Now they are sting up and falling off. Here's a photo of some that's now drying up

I think floral_uk is on the right track - Euonymous alatus, Syringa (but I believe vulgaris - the reticulatas I've dealt with have a slightly different leaf) and probably the small tree is Cornus alternifolia, a dogwood.

Do beware of pruning the dogwood now. Late fall and winter are infinitely better when it's dormant. The sap it will bleed now is a great attractant for insects and disease. Otherwise, the Euonymus and the Syringa would be fine to prune now.

I agree with all 3 of ging's ID. Be aware that the Euonymus may be invasive in your area; meaning that birds eat the tiny berries and then deposit the seeds where ever they fly. Dropped seed will sprout also, so you (and your neighbors) will be pulling up volunteers in many places in the yard based on what I see here.
