"Holy shit" and "Jesus Christ" are both crude exclaimatons of surprise, fear, anger or other strong emotions. They are not used in polite company but may be used in casual, comical situations.

You are only supposed to use his name properly, either to ask for salvation or in prayer.
"What a fuck" is not a common phrase. "What the fuck?" or "What the hell?" are crude phrases which mean "I don't understand"; 分かりません。 "What on earth?" is much more polite.
