I have a group project in school. My group mates want an alternate blinking, rapid blinking and fading LEDs in our project. The thing is they want it to go simultaneously. Is there anyway I can do that?

If you change each led in order they will change fast enough that you cannot tell. The lag between changes will be on the order of microseconds.
If you want to dive into direct port manipulation you can change multiple leds at the same time. Though not all at the same time instead they are grouped.
Not really. Because it can execute only instruction at a time. But due to the persistence of vision, you can always fool your eyes by processing leds so fast, in the order of microseconds. It will make us think that all LEDs are controlled at the same time.
