trees or bushes

I was given these to trees/bushes when they were little more than sprouts, This year they have decided to bloom!

I would really like to know what I'm growing. :(

 

#1 is a willow, Salix spp.. A photo of the overall tree/shrub would help, but willows are notoriously difficult to ID.
#2 is a fruit tree of some sort... likely a Prunus (sour cherry, plum) but a focused picture would be very helpful.

 

Here are 3 more pictures of the one type.
I hope that they are clearer.

 

Continues to look like a plum.
