Purists will tell you that the gerunds require the possessive, but this is being used less and less often. You will find people who tell you that there is a difference between being pround of HIM instead of HIS ACTION, but very rarely are such difference intended by the speaker nor noticed by the listener.
So while you can substitute in "him" be aware that some people will find this a lapse in grammatical correctness. Others find the original to sound stuffy. I personally would prefer "I was proud of him for not getting scolded by his teacher" instead of either of those. (But then, I have higher expectations for my children, so simply not getting into trouble would not exactly be a source of pride and joy.)
More natural, to my ear, for the other two:
She insisted that he accept the gift.
She complained (note the tense) about his call last night.
There's also no need for the "having called" instead of "calling."
And lastly, drop the "up."
