What do you call these?

1 roll - if it were larger and flatter it would be a tea cake (not to be confused with a current teacake).
2 dressing gown
3 ginnel
4 crust.

I'm from south yorkshire, although I now live in Lancaster, my wife (from Lancaster) agrees with me on these except the tea cake which apparently (although she's wrong) always has dried fruit in it and you don't need to qualify it, if it's no fruit it's not a teacake according to her.
