I see that you edited your post after I answered, possibly in part due to the use of overlapping labels in my example. Labels are a very powerful visual feature in yEd, but can be frustrating at times until you learn how to master them. Here are some tips to make editing labels more comfortable:
1. Hold down CTRL when clicking to select a label on a node. It makes it easier to differentiate between labels, especially when they are stacked on top of one another.
2. When building a node with multiple labels (including those that contain icons and symbols), build the pieces separately as nodes. Drag each new node piece onto the node and then right-click to select Convert to Label. You can convert back by selecting the label and then choosing Convert to Node from the right-click menu, but this resets any Placement settings for the label.
3. If the node has no Text in the primary label, then the first label added will become the primary label. To prevent this, ensure that you enter text into the node's primary label or Text property before adding additional labels. The primary label is the default one that you see when you edit the node's properties.
4. Labels stay fixed in size, even if the node is resized. You can use the Placement property to make a label stay in the same place relative to the node's top, side, or corner.
5. Use the Distance and Insets properties to fine tune the placement of labels relative to the placement on the node. Insets are TOP LEFT BOTTOM RIGHT pixel measurements to shift the label, so for example, 20 2 0 0 shifts the label contents 20 pixels from the top of the placement and 2 pixels in from the left of the placement.
6. When a Label or Node is selected, press F6 to access the Properties dialog. This is often the fastest way to access all of the properties.
