I am using Ubuntu 12.04 and the update manager appears daily with updates. I am ok with other updates but I want to know about Linux Kernel updates: Should I update to new versions, and why?
You can install any kernel you want. There is no problem on using one or multiple Kernels at a time. But sometime you should consider the Kernel Mapping to your Ubuntu Version. For example following link lists out the mapping of different kernel to different version of OS:
Ubuntu to Mainline kernel version mapping
You can get a complete information of Kernel installing/removing from following link.
