I should add, that none of these has any fragrance I could detect. Both the white and the yellow are tall, the white one has canes easily 8ft long. It's contained in an iron railing cage as you can see. The yellow one is about 4-5ft tall and is probably some kind of tea as it has slender tea-like growth. None have received any care for some years, so they must all be very cold hardy as we had single digit temperatures last winter for three nights in a row.

Hi! I am not a great expert or anything, but the cute little single pink and white one in the bottom photo looks very much like Ballerina.

The second one is probably a tea, as you said.

Safrano is one possibility, which was introduced in 1839.

I'll put a link to the HelpMeFind photos. You can click on the Description tab for more information -- see what you think:

Thanks for looking.

I believe the pink one is Ballerina, just looking for objections or confirmations.

The yellow one might be Safrano. I was also thinking of Lady Hillingdon as a possibility.

No ideas on the white one.

Last one is even showing the big inflorescence of a 'Ballerina'. Next step would be to cut some specimens from a known 'Ballerina' and take them to the Bigelow property, compare them with the plant there.
