Biscuit joint: a biscuit is a pointy circle of wood. A fancy saw cuts a slot (arc-shaped) into both joining surfaces and the biscuit is slathered with glue and everything assembled.
A lap joint is one where another piece of wood is placed over the joint and this is glued to both pieces -- looks like a set of brick joints. Extreme lapping would involve having 2 sets of parts and assembling a double layer offset by 1/2 a piece, again like 2 courses of bricks.
I'm not sure about a half lap -- some of the board is removed and two thin pieces are joined?
