Your plants look beautiful!
Easy solution, purchase 3 or 4 inch pots, peat pots would even be great.
Move the small plants into the new pots using a good commercial potting soil.
This will give each plant the room to grow until you can plant outdoors.
Place a small stake in each pot.
You mention you are in Illinois, which has growing zones from 5a to 6a in the southern part of the state.
Cypress Vine is hardy in zones 6-9.
