Can TD creates point sizes and alpha values of point clouds randomly for each point?

I got curious about something while studying point cloud with TD. It is about whether TD can adjust the value of each point size and alpha value. If this is possible, I would really appreciate it if you could tell me how.

Yes. To get your started, see this post with examples for the pointField component in Palette.
