Thanks Aquawise. I think the second one is Indian Chief.

The last one looks like Amas.

I think the third one is Cardinal, especially after looking at it growing outside. So we have: unknown, Indian Chief?, Cardinal? and Amas?.

Found some of your pictures

No the third one is not Cardinal, it is probably Mme Henri Cayeux. Check for PBF, Mme Henri has alot. And Cardinal has none. Mme Henri is very aggressive and grows quite freely. Cardinal is a bit of a slug and hard to propigate.
The first one may be Blue Gown or possibly Missouri.
