The first one that was mentioned as targeting should be IMO only a UNR if the rule states you have to lead with an open hand. There was clearly no contact to the head or neck, just a BSB. The big hit at the end I don't think could have been targeting as you even said, the contact is to the high chest. As has been said many times a crouch and upward thrust are not fouls in and of themselves, but they must be done in conjunction with contact to the head or neck.
