Yes stronger magnets will increase the efficiency of the dynamo,
for the same number of revolutions per minute greater power will be produced,
the voltage and current are a factor of the number of windings at a given speed, they are inversely proportional, increase the number of windings = higher voltage,
higher voltage reduced current.
To increase Voltage and current you must increase speed of revolution. producing more power.
IE. more power in more power out.
since P=IV power = current x voltage you must increase power to increase current and voltage, If you increase the efficiency of the dynamo you should get increase in the power output for the same power input.

NO! It's the metal thats goes through the magnetic field and the number of loops there are in it that determine the voltage and current strength.

current would depend on the load placed on the circuit, Voltage and current would increase given the same rpm and load.
Rainyday it also depends on the density of the magnetic field!

Surely yes. because the amount of electrical power produced is proportional to the flux value of the field magnets used.

higher current voltage unchanged.
