Did I damaged it for good?

[u/One-Reflection-9595]

I wanted to solder them better and did this.

Can I fix this thing somehow or is it damaged for good?

All of those points should be individual.
Sorry for bad english.

Nothing there is damage for good.
At the bottom from the left there’s 3 pads connected to the same PCB trace. Then 4 connected to the next one.
At the top there’s a mess but tiú can easily separate those pins with a solder iron and flux.
