As you have probably been handling them unaware the ringworm was "brewing" then please be aware that the ncubation period is typically 1-3 weeks but can be longer - It varies with the site of infection - skin infections appear more quickly than scalp infections. Although the likielihood is small that you will contract it......it cannot be ruled out.
As for handling once they've got the all clear from the vet- strictly speaking you should be able to do so straight away - However on a cautionary note I would ask if you can tell us what treatment they are recieving....some are more effective than others and, depending upon the treatment they are receiving, I might suggest waiting for a period of time to ensure it has been properly eradicated?
As mentioned in other posts, observe strict hygiene measures - wear sugical gloves, plastic apron, avoid touching your face/skin whilst handling the piggies and wash wash wash!
You would be better off using F10 disinfectant instead of bleach - the manufacturers state it is active against ringworm spores (not many are) and it is not harmful to piggies, hoomans, clothing or carpets!
I do hope this unfortunate issue can be quickly resolved so your family can enjoy their new friends....(and please check any other pets you may have)

PS -touch wood - never caught it from my own pigs ....or when doing rescue uplifts of pigs in poorly condition.
