What you are trying to do is swim upstream against a current. Yes, you "can do it" the question is, how much work do you want to do to do so?
In terms of presets, you can have LR save the presets as part of the catalog instead of the user preferences. That option will give you access to the same presets and templates on both accounts. But, in order to have the same DNG profiles & lens profiles available in both means those same profiles will need to be stored in the each user prefs.
This Adobe tech note will tell you where LR is storing the various files: Lightroom Help / Preference and other file locations in Lightroom 5
You'll need to manually copy all of the files and folders from the one user account to the 2nd user account.
Are you really sure you want to do this? Every time to change something you'll need to recopy all the stuff over again. Seems like a lot of work for little gain...
