There is no "right permissions". What permissions you need depend entirely on what you want to do.
On a directory, 'x' permission allows people to cd into it, 'r' allows people to ls in it, and 'w' allows people to create or delete files. Read permission is 4, write permission is 2, execute permission is 1. Decide what permissions you want, add them up, and you get a number between 0 and 7 inclusive.
Do it three times. The last number applies to random passers by, the middle one applies to people in the group owning the dir, and the first applies to the actual user who owns the dir. Don't think about who you want to restrict -- think about who you need to allow, and grant nothing else.
Having done that, you have three digits, like 740. That gives full permissions to the owner, read and ls permission to the group, and nothing at all to anyone else.
For a temp folder or test folder, you'd also want to use the sticky bit, chmod u+s, on the directory itself. This changes how directory permissions work so that files can only be deleted by their owners, having simple write-permissions to the directory itself becomes no longer sufficient.
