My mesh is parented to an armature. But when I rotate the armature upperarm, the mesh's upper arm does not follow the armature fully.
What are the likely causes and how to fix this?

It looks like it's a bit messy in your vertex groups and bone weights, for example if I select a group like Chest (which is duplicated by the way), but also some other bones, then press the Select button, I can see that the arms are part of these groups, maybe not enough so I can see it in Weight Paint mode, but enough to have influence on it. So maybe check all your groups, remove these vertices from these groups, or delete some bones and/or weight paint again...
I had similar issue . I deleted other vertex groups that are not suppose to be included for he particular mesh. it was the eyelid that I was having issues with. so I deleted the vertex group for finger and lips for that mesh, weight painted and it worked. N.B. I didn't delete the bone group
