What are the differences between the two? I need to send an email to 5 different people.. however it won't let me use commas in "to", but it does in "Cc".. why and how?

You should be able to put multiple address in the TO: field. Try a semicolon after the address. Or just a space.
 
Beaten to it. 😛

They don't do terribly different things, but the idea is that To: means the person to whom the message is being addressed. CC: means carbon copy -- it's a copy of the message being given to a person who is not being addressed by the letter.

However, in most mail apps, you should be allowed to put multiple people in either/both the To and CC fields.
 
Also:

BCC: means blind carbon copy. use this if you don't want all the people you email to know everyone you sent the email to. (hides their email addresses)
 
I use CC in two cases:
1. When I'm sending to multiple people and I'm expecting some but not all of them to reply to me or to take action based on my e-mail.

2. When I'm replying to an email from one person but keeping other people "in the loop", even if none of them need to reply to take action.​
In case #1, I use the TO field for the people who need to act, and CC for everyone else. In case #2, I use TO only for the person I'm replying to.

When it's not case #1 or case #2, then I use TO for everyone.
