The second is unacceptable if it happened as told. I don't know what to think of the first point without context. The third point seems like an innocent joke to me, if slightly inappropriate.
I don't mean to defend him from any kind it accusation, but all of this is meaningless without full context and hearing the story from both sides.
Hence "if it happened as told". These kinds of allegations are tough because while these things do happen, they're also strong enough allegations that they require serious proof, while also being essentially unprovable. I never know how to feel when something like this comes up since on the one hand I don't want to discourage victims from speaking up, but on the other hand, no good ever comes from them.
