The most efficient way is to to use a dichotomous key that is specific to identifying trees by leaves and branch structure. Which will help you narrow them down by characteristics. Your goal would be to find a dichotomous key that would contain all those trees .
There are some cool websites out there meant for identifying trees also, such as this, https://www.arborday.org/trees/whattree/
Hope this helps! Let me know if you would like more help :)
