Can someone explain the MacArthur/19th-12th Oakland station configurations?

Trying to understand/wrap my mind around how these operate with three platforms (19th St/12 St Oakland) and four platforms (MacArthur). What lines operate on which platforms? At what point does this reduce to two tracks again and which track goes where?

Bonus points if you can help me understand Daly as well (with two northbound and one southbound)

Are there any other funky 3+ platform stations I'm missing?
