Components missing on motherboard (no display)

Hi, after many researches on this site, and there is so much different problems, I think I have an other problem.

So after replacing a screen really ruined, i've must break these tiny components and i wonder if i can replace it by soldering with a fine tip (0.12mm) ?

and what are these different components of course ...

thanks for the help.

(I guess it's my problem because just before removing the broken screen it worked)

Here are the 3 components (lost 1 of them but I suppose that is better to replace it because of the adhesive on it ...)
