Most people normally take their ratios from the deadlift as it's the strongest exercise you should have.
Assuming the deadlift is at 100%, your back squat should be around 70% of that, bench press around 50-60%, your clean and press is tricky as it will be limited by the press and not the clean (but your oh press should probably be around 50%), pull ups at around 50%.
This isn't an exact science but a reasonable approximation of what you might aim for.
First reaction though? Your bench press strength is way out of whack with your deadlift and squat strength.
