Can I use it with different pins at the same time? (s32k144w timer and pwm )

I made PWM on PTE8 using example file on S32 DS and I made a separate code to toggle by repeating 0 and 1 on pin PTB5 using example. But I'm trying to combine the two codes into one code.
This is the code being tried.

I can't express all functions with this code

Instead of 1 and 2 being executed independently, 1 and 2 are executed quickly in order by the loop syntax, making it mistaken as if a signal is coming out at the same time.
Is there a simple way to do this independently?
For example, through for, while, and if phrases

I don't know if what I'm trying to say is conveyed well, I need your help.

Do be honest, I really don't understand your issue too much.

If you call two functions sequentially than it'll be also sequentially executed. Please clarify
