Gracie, I almost see pug and beagle.. maybe some JRT. She reminds me of Brandy.
Gabby - Field bred Lab. Plus something with a typically red coat.. I bet Chow. Really, definitely chow. Her coat looks like a chow's coat to me except shorter, I've seen loads of chow mixes with coats like that.
Lucy.. uhm.. no guesses... spaniel? Maybe?
