Sorry life is not that simple. The things are interrelated and don't act on their own.
The direct effect of increasing turns is to increase voltage off load (EMF) . When there is a circuit and current is flowing then anything can happen depending on the conditions.
Increasing the wire size reduces the resistance, which gives you the ability to produce more amps for the same amount of losses ( heat in the stator)
If there is a circuit and there is current flowing then increase in speed will increase the current. If the load is other than a battery then volts should rise as well, but if the load is a battery with dump control then the volts may be held constant.
I know that this doesn't help you but it is better to try and understand rather than work from a series of assumptions.
I assume you are thinking about battery charging and what really happens is this.
For a given set of magnets you need sufficient turns to reach battery volts ( rectified output) at a chosen cut in speed, the lowest speed at which you get current.
The winding space will dictate what thickness of wire you can get in with the chosen number of turns. Then the resistance of the winding will decide how many amps you get at each speed.
If the current is less than you want you either go for more magnets or increase the cut in speed and try again.
Bear in mind that that this also needs to be linked to the type and size of the prop so that it can produce the chosen speeds with the wind available.
If you are new to this, base your experiments on something that works until you gain enough experience to be able to predict what effect changes make.
