The first one, I think, is a type of buttercup called 'Buttered Popcorn'.
(Ranunculus repens 'Buttered Popcorn')
I'm not sure though...would like to see it in bloom.
Personally, it is WAYYYY too invasive for me.
Very perennial.
The second one is Salvia 'Hotlips' like Mike said.
(Salvia microphylla 'Hot Lips') Perennial in zones 6 and up.
And the bottom one with the purple blooms is a Verbena.
Probably Glandularia canadensis 'Homestead Purple'.
Might be perennial for you if you have a mild winter.
