18.04 – You cannot use the original disk size in Ubuntu

I have 1 TB of disk space on my laptop. Previously, I was using Windows10 and a few months ago I installed Ubuntu. In the disk usage analyzer, it shows something like this.

Now, Ubuntu is clearly localhost. And I don't know why they are 153.7GB. I want to enlarge the size Is there any way I can do that?

Update: 222GB and 141GB were listed as UNMOUNTED but when I clicked on them, I could see the previous files I had used in Windows10 (some movies, softwares, songs, etc.). Now, these two volumes are on my desk. I do not know what happened.
