Dll files are like 'mini-programs' that run certain tasks associated with particular programs (or groups of programs). Windows includes lots of them and others are added when you install further software.
Comodo has recognised 1014 files as being part of Windows, or associated with programs that it knows about, and checked that they're what they claim to be. However there are 14 remaining files that it simply hasn't heard of. That could be because they're hiding something nasty but, given that they've been quietly sitting there for several years, it's FAR more likely that they're simply part of some software that Comodo doesn't knowabout.
In particular, some of those files (such as epfunct.dll) were probably added to your computer's registry when you (or a previous user of your computer) installed a Lexmark printer.
I can see nothing there which would worry me. I'd simply ignore the presence of those dll files. (They seem to be doing no harm and they take up minimal space on your hard drive. Removing them would risk a program on your computer ceasing to work properly).
