what are the different among ( UBUNTU ), ( UBUNTU,with Linux 4.4.0-28-generic), ( UBUNTU,with Linux 4.4.0-21-generic), ( UBUNTU,with Linux 4.4.0-31-generic) ?
Which should I use ?
Do I need to keep all of these in boot menu ?
You do have an extra kernel. To remove it and update grub in terminal:
sudo apt autoremove && sudo update-grub

It’s different kernels. Ubuntu will automatically try to boot the latest kernel. You don’t have to do anything. Ubuntu will save a certain number (2 I guess) of “old” kernels in Advanced options. You only have to use those kernels to boot if your latest kernel update fails.
I don’t know what your boot screen looks like but normally it provides an uncluttered view with old kernels under Advanced options.
@Wimpy There is a problem with Ubuntu MATE. It says Ubuntu instead of Ubuntu MATE in GRUB. This can cause confusion in multi-boot environments.

You can also run the following terminal command (Ctrl + Alt + t) to re-install Grub:
sudo apt-get remove grub-pc && sudo apt-get update && sudo apt-get install grub-pc

is there risk doing this ? And which one is the latest ?
Why manually remove kernels?
This is dated but still good for the most part.
