Q: I accidently deleted messages that I wanted to save.  I have IPHONe 5c.  Any ideas of how to retrieve them from Icloud?

You cannot just restore your messages only.  Backup/Restore is an all or nothing process.  Follow this procedure:

Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

Of course, make sure you have a backup in place first:

The only other recourse is some third party software that may be able to restore only your messages.  Something like:
