Photo 1 - tree 1.
Photo 2- tree 2.
Photo 3 - tree 1.
Photo 4 - tree 2, with the trunk of tree 1 in the background.
1 is dead straight. 2 looks as if it's suffered a bit of misfortune, & the top has been damaged & bent over, but otherwise is pretty straight. See the pictures for branches: look like bog-standard tree shape. Sticking out sideways & pointing up a bit.
The leaves differ a little between the two trees. 1 (the undamaged one) has slightly smaller, softer & brighter green leaves than 2. The colour & surface texture differences in the photos are real.
The last photo gives the best view of the bark of both saplings.
