Due to long names, the nodes will be jammed like this. So I have several questions in mind:
1. How to insert linebreaks into the nodes?
2. How to adjust the fonst size?
3. How to adjust the distance between nodes?

Thank you

You can do all this by modifying styles.

1. You can use \\, but add an alignment option, such as align=center.
2. Add an option such as font=\small.
3. Adjust a distance value, such as level 1/.style={sibling distance=6em}].

A complete example with the changes:
