Use other volumes space for root

I have a too limited space for home so I get regular pop up to ask me to increase its size below an image of the scan

I have several discs, on one of them is the Windows OS, but still I have plenty of extra space on some of them. How can I move the partitions so I will improve the situation of root?the different discs I do not wish a priori to move home to another drive I would prefer to reduce the size of one disc, sda2? sdc1?, to increase that of "computer". Here is the output of lsblk -f -e 7
