When editing a system, you have to click at the Central celestial Body, wich should be Juno. Then click the replace Button (the third one i guess). That should Open a window where you can select an other object from the list. If there are no objects in the list, you must activate the search filters by clicking at the 3-point Button.
Select your favorited Object and Juno should be replaced.
To add several planets to your system, again select the Central Object of your system, then click the add Button (that one with the + ) and select your Planet. To add another Planet you need to select the Sun again, then click add Body, and so on.
After adding a Planet you have to adjust the distance to your sun, because it is very far away from the Sun.
To add a moon to your Planet, select a Planet and click the add Button, the Rest is the Same.
I hope that helps a little bit, and sorry for the horrible english, but its not so easy, 22 years after finishing school 😁.
