Types of Mutual Funds According to Dave Ramsey

So I've been listening to Ramsey Show lately and honestly I'm a bit confused on the types of mutual funds Dave suggests. He says 1/4 in aggressive, 1/4 in international, 1/4 in growth, and 1/4 in growth and income. What do each of these types of mutual funds mean? I had assumed you would just follow the S&P 500 and whichever index is offered by a company such as Vanguard. Would it be possible to get some examples of each of the types of mutual funds Dave suggests that could be invested from Japan either from the Japanese brokerage or another international brokerage? I'm Canadian for reference. Thank you in advance!
