Does the ruling for someone who deliberately breaks their fast in Ramadan apply to me, given that I had three wet dreams in one day, and during the third time I was semi-awake and held my penis with my hand?

The ruling for someone who intentionally breaks their fast during Ramadan does not apply to you, because the emission of semen occurred unintentionally on your part. Your waking up from sleep or drowsiness at the moment of semen emission does not affect the ruling, as you were not the cause of its release.
