You have two infections neither of which is serious.
The spots that form on Oncidium in abundance is usually Phyllostictinc pyriformis fungus and relatively harmless, although, unsightly. On some Oncidium like the Chocolate orchid Onc Sharry Baby they appear in the thousands. It has very little if any effect on the health of the plant. There is not much you can do to prevent it.
Some of the spots look like they were insect bites (indented into the leaf.) It also looks like any secondary infection that attacked there has stopped.
You plant should do fine.
