I hate to say it, but if that’s a median example of what your leaves look like, you need to get rid of this plant. IMO it’s too far gone.
Not sure what the other insects are besides the two spotted spider mite. At this level of infestation, you’ll never get rid of them entirely. You may be able to keep them in control by spraying every 2-3 days. Guess it depends on how contained you’re environment is, and how much work you’re willing to put into this plant. So sorry buddy, and good luck in whatever your choice of treatment is🤞
