Flower ID help

Flower ID help

I've been reading the community for a while, but this is my first time posting. I used to do balcony gardening, but bought a house last year and am just gradually getting the garden together. I've inherited a batch of flowers from the prior owner, many of which I don't recognize. I'm wondering if anyone here can tell me what these are? This is probably about knee height, and has just started opening up these gorgeous pink flowers: This is almost past bloom, so I'm not sure how recognizable it is- it's about 3 feet tall, and the flower were in groups on long stems. Here's a closeup of the flowers: Finally, this has really pretty feathery foliage, and I thought it was just a ground cover till it suddenly produced flowers. Most are this pale pink (they look nearly white in this picture, but aren't), but some are light yellow and some a darker pink. Many thanks for the help.
