Hello Irinnie,
* right click on the panel in the empty space to the right, where there are no icons.
From the menu that appears, select Properties.
On the Separator GUI tick the box "expand".
Click Close.
From the GUI in your screenshot - (right click panel>panel preferences>items tab)
Click the tab named "Items"
Click once to highlight in the list "Clock".
Use the downwards arrow to the right side of GUI, click it repeatedly until the clock is moved to the right corner.
Repeat the same for other icons you wish moved to the right.
Click the "Display Tab", tick the box "lock panel".
Click the Close button.
*If you do not have the option to expand the separator or there is not one -
Go to the items tab, as above -
Click the "+" icon to the right
scroll down list to "Separator", highlight it then click "Add"
Highlight it in the list of panel icons by x1 left click on it, use the up/down arrows to place it next in the list below the "Window buttons".
It should look similar to this, "workspace switcher", and "notification area", if missing can also be added in the same way as the separator -
