Ubuntu – How to resize a Windows partition after Ubuntu installed

dual-bootgrub2partitioningwindows 10

I have a new laptop which came with Windows 10. I managed to make it dual boot with Ubuntu 15.10. Unfortunately I left the Windows partition(s) too large when installing from a USB stick loaded with 64 bit 15.10. My hard disk, which does dual boot from grub has the following partitions:

The partitions 3, 4 and 5 belong to Windows I think, whereas 6 is my Ubuntu partition. Is there any (safe) way in which I could shrink/move the Windows partitions and make the Ubuntu one grow?
