[SOLVED] Triple OS partition cleanup

[SPDESIGNS]

Hello, i've installed Windows 10 on my computer as my main OS and then installed Ubuntu and Deepin alongside it. Now i want to cleanup the partitions that contain the data for the Ubuntu OS but i don't know how to check which partition contains which OS. Is there any way to find out using a partition manager like the one in the image? Is there enough information here and if so how do i tell which is which?

Linux will not be located on NTFS partition.
So some of those green ones would belong to Ubuntu.

Thank you very much for the reply! Is there a way to know which one belongs to it or should i delete randomly?
Truth is, i remember allocating around 100GB for Ubuntu and another 70GB or so for Deepin so it seems kind of weird that those three partitions sum up to only ~98GB. Could one OS override the file of another OS?

Most likely - those another 70GB for Deepin you took off from Ubuntu.
