I'm not great with caterpillars, but the top one looks like Garden Tiger, I'm not sure what is wrong with Buff-tip for the third, and the bottom one looks like a Drinker.
I think the 3rd one is also a Lackey. Big web suggests this species, and wrong time of year for Buff-tip?Agree with Dave on the others.George
Told you wasn't good with caterpillars!
We also had some nice Latticed Heath on the wing at Twlc Point. To be fair to Emma she called Drinker at the time we found the bottom one!
