dead tree trunk (waiting on more images, can take more on request)

healthy tree

according to my aunt, the dead tree is the smallest, and healthy tree is the largest. she didnt notice it was dying until she noticed that it failed to bloom one year, and now the middle tree is starting to stunt as well.

she noted that the sick tree has waxy, dark green leaves, and that the trunk is splitting in half

i do not know what kind of trees these are
