I think Dolphin Experience has around 16, but it's really hard to pinpoint the number.
Dolphin Quest Oahu has 4.
(Hi'iaka, Hoku, Liho, Mahina)
Dolphin Quest Bahamans has 9.
(Bailey, Heydon, Somers, Cirrus, Nimbus, Dolber, Khyber, Malabar and Caliban)
Dolphin Quest Hawaii has around 11 - I don't know the exact number.
Dolphin Quest Morea has more than 4 - again, I don't know the exact number.
(I'm currently researching Dolphin Quest)
I know of at least 4 cetaceans at Sea Life Park, and I'm sure they have more bottlenoses. Two of those cetaceans are Keikaimalu, the hybrid, and Keauhou, a melon headed whale.
I don't have more than that, sorry. =\
