The others are so obscure and it would take a palm person in the bay area to say what might be wrong in that list.
African Tulip tree grows here Brandt- into a tree too. I know that ex Hayward citizen Delonix on the palm board has told me he had those growing at his home in Hayward.
I had Mammy grow well all summer,make it fine through winter 2015,grow great all the next summer...then last years cold AFTER all the December rains,got it.
I was told that Ficus Bengahlensis and Ficus altissima can grow in the bay area. I wish I had tried..but a tiny lot is hard to fit Ficus into.
Also- the south bay is where these plants did well. I've seen photo's Brandt of Plumeria growing in ground in Santa Clara. It was about 3+' tall and about 5' wide. A Celadine. Santa Clara I've been told- San Jose too,have some tall trunking Majesty Palms. I was surprised to see Howea in San Jose doing well.
Ficus lyrata might be a stretch..or I could be wrong. Seems like even when a die hard like me says "No,too tender"..I see one,one day.
I know some cycads like mine C.circinalis,and the tree Euphorbs like E.ammak were supposed to not grow here. They seem pretty permanent to me. I mean Im not frost free- but neither is the L.A. arboretum and they go with many tenders. SO far I've gotten a dozen years out of a Pachypodium lamerei growing in ground..even through 2007,when it was half the size it is now,or less.
