How to unlock a folder.

Can you see the permission on those files? Try to right-click on the file -> Properties -> Permissions tab and see the owner of the file.
If you haven't the write permission, try to
sudo chown user:user file
sudo chmod u+w file
(obviously substitute user with your username and file with the filename of the document.

Sometimes documents don´t visualize exactly the same in Open Office as they do in MS Word. This is a font related issue. Please install the additional font package. Open a Terminal from Applications->Accessories->Terminal and type

sudo apt-get update
sudo apt-get install cabextract
sudo apt-get install msttcorefonts

Question one - All of the files on a system have permissions that allow or prevent others from viewing, modifying or executing. A user has full permission and access to any files that they create. Since this file came from Windows, linux is not recognizing the user as the owner of this file and you do not have permission to access them.

Question two - You can change the ownership and permissions.

Please read https://help.ubuntu.com/community/FilePermissions

For folders you can user the -R option to recurse folder. Just be careful when use this ( If this is done on a folder with a symbolic link to another folder, that folders permissions will also be changed).

Ex. for home directory.

sudo chown -R user:user /home/user
sudo chmod 755 -R /home/user
