Would it be possible to get audible alerts (chime) and not just text for opened doors?

The short answer is yes. The longer answer would depend on the type of hardware you have. Do you want the chime on your phone? Which phone do you have (Android, iPhone, Windows).

Could it activate the bathroom exhaust fan after the humidity sensor hit a target % let say 55% humidity and run until the humidity go down to 45%. Or this would be like a timer turn on at 55% and run for let say 10minutes instead of using the humidity sensor to turn off.

And any of the zWave or Zigbee switches supported by smartThings.

And maybe this app:

[OBSOLETE] Bathroom Light Control

Bathroom Light Control Initial Release: 1.0.1 Controls bathroom lights: Turn on light when motion is detected. Turn off light after x minutes of no motion detection Extend light off timer to x minutes if humidity sensor is above the average for the room and trending upward (shower in use?) Developed / Tested with Aeon Multisensor which by default sends humidity every 8 minutes. We need to detect that humidity is rising with 1 reading as most people will want this to kick in by the 8 minute period and not 2 polls which would be 16 minutes. To do so we calculate the average temp over a period of readings (4 by default), then if the humidity is higher than the average and higher than the last reading, it is determined that humidity level is trending upward, so we adjust the off timer to…
