No. If you have one set of tyres which is larger than the other set, only one set will be bearing that weight. This is going to cause undue stress and wear on your tyres, and could very easily put you in violation of weight laws, since those specify the area of tyre which much make contact with the road to safely distribute the weight without causing damage to road surfaces.

Is it ok to have 3 tires the same ratio and 1 different on a car?
By ratio if you mean size, the answer is no unless the car comes from the factory with a different size rear tires than front tires like some sports cars. In that case you would have 2 tires the same size on the front and 2 tires another size on the rear. You should never ever run 2 different size tires on the same axle. Therefore you would never have a situation where you would have 3 tires one size and then 1 tire another size.
Can a 205 70R15 tire be mixed with the other 3 tires 215 70R15?
NO, absolutely not. Never, ever, mix tire sizes on the same axle. You could put a set of 215 on the front and then a set of 205 on the rear but not a 205 & 215 on the same axle. Tires on each axle must be the exact same size.
