What type of elm

My neighbor picked these up for $5 each at a nursery since she knows I am interested in Bonsai. She was told that they are some type of Elm.
Thoughts of what #1 is and what is#2.

#2 looks like a zelkova, aka grey-bark elm. #1 may also be zelkova though it’s harder to say as the ends of the leaves are rounder.
