Getting values from dynamic input fields

I have created a custom single field using a tutorial here and the value is being successfully shown in the cart and checkout pages as well as the order email.

I have now created some dynamic input fields so that its shows the start and corresponding end time, and a user can create these using the add button (like in the image below)

Now i want to get those values and output them in the cart, checkout and thank you page and in the email as well.

The values should correspond like lets say the user has added 3 dynamic start/stop fields the output should look something like:

Start: xxxx Stop: xxxx
Start: xxxx Stop: xxxx
Start: xxxx Stop: xxxx

Your help would be much appreciated.
