More effective way to copy/paste layer style is to set up shortcuts.

Find menu:
Edit > Keyboard shortcuts > Application menu > Layer >
 

Set up shortcuts:
Copy Layer Style – Cmd/ctrl + Shift + C
Paste Layer Style – Cmd/ctrl + Shift + V
Clear Layer Style – Cmd/ctrl + Shift + X

Select layer in layers panel and press Cmd/ctrl + Shift + C
Select other layers and press Cmd/ctrl + Shift + V

Hint: you can set up shortcut for 'blending options' too, but it's better to set up 'Drop shadow' shortcut or other option that you use often, than 'blending options'.
