Unknown folders in C: users? And User profiles that won't fully disappear?

Ok so there are these hidden folders in my C: Users. I'm using windows 7 - lenovo pc. These user folders are named something like TEMP.lenovo-PC, TEMP.lenovo-PC.004… Etc. Something like that. Now they have a lock button, and when I open the folders inside (even though I have admin rights), it says access denied. Is this normal? Or it is some kind of virus?
Also are the folders: default users, default, and public, a normal occurence in C: users?

And lastly, I deleted two of my user accounts, because the profiles got corrupted. And while they were gone in the log in page, as they should. These user profiles still show up on drive C users? With all the content and all, still visible and accessible (even if I deleted these profiles-and I did not choose "keep files"). Why isn't it fully deleted? Is it a sign of hacking?

Thank you so much, I'm just not familiar to all these.

Hi

In win 7 the admin rights need to be elevated to perform some actions.

This is done by right clicking on the folder and selecting the "Run as Administrator" option.
