I was trying to place a larger memory size be re-balling, and I accidently knocked off the caps / resistors highlighted in red.
Do I need to replace these? Or can I ignore?
If I have to replace, how can I identify them?

Probably, especially if the device isn’t working now.
You will need the schematic or parts placement diagram to figure out what values to replace them with.
@YellowDog, I havnt attempted to turn it on since.
Would it be fine to switch it on and seee if it functions without them?
Ive read numerous times over the years some of these small capacitors/resisters are negligible, and don’t need replacing in most circumstances.
This is common in the laptop repair industry, to leave broken 0402 caps broken.
I’d give it a try, what do you have to loose?
The single arrow to the right is an inductor used to match the antenna. Without it, wifi/bluetooth won’t work. Probably OK without the caps (double arrow on the right) or you could try 100n for the small one and 10u for the larger (just a wild guess). I can’t tell if the part above is a resistor or cap.
Best bet would be to look at the datasheet or the schematic for a similar board

Wasnt sure if it could damage some other parts as those above are missing?

I managed to resolder the top left SMD, and have powered the device on.
It seems to be working fine so far.
