After some research I have concluded the following.
The reason for my question in the first place was that I hade the impression that there were only two timer channels. That is not the case. Each of the four timer timers have two timer channels. With that information and the wipy pinout it is clear that at least three pwm outputs can be used independently and simultaneous.
Timer 2 and pwm3 is connected to the heart beat and is not so easy to use as it lacks an easy connection.
If your application allows time sharing of timer 3 between channel A and B then four pwm outputs can be used in the application.
A note about simultanous, because of set up time the PWM outputs are not exactly simultanous. I have not checked if the outpus are in phase with each other if they have the same frequency and duty cycle.
