Hi everyone, I would need a help regarding the state of the cogs on this bike. It’s a second-hand bike I’m going to check, and I’m not sure if this is ok or they should be replaced?

Assessing tooth wear from pictures is pretty much impossible unless it’s extremely worn and assessing tooth wear from pictures with a low a resolution as these is impossible. You should measure the chain wear/stretch and assume the chainring & cogs are worn to the same degree.
Looks okay but used to me, I would fully degrease and clean the drive train. Add a new chain with a good lubricant and then check the rear derailer alignment and adjust it if needed. Then go on a ride and see how the shifting performance is and if there is any chain skipping.
