I am pretty much in the same boat, however, I haven't done units 1 and 2 since our school doesn't offer them. My holiday homework is similar, but we did all our definition things in orientation so we have to find 10 global actors in the news. In you case, I think your teachers are asking you to find global actors which have put 'the three national interest that go beyond any political leader,' which is economic stability, national survival and preservation of culture. Since you only need two you have it quite easier, and they don't have to be recent either!
I am not sure if you went into this much detail, but for non-state actors you have heaps of sub categories, such as TNC; which stands for Transnational Corporations which are any organisations which are based in one country, operate in more than one country (e.g. Apple). You then have NGOs; non-government organisations, which are organisations which are created by the population and operate independently from the government (e.g. Oxfam Australia). You also have IGGs; institutions of global governance, which are institutions or rules that seek to manage relations between states. (International Monetary Fund).
So you need to find examples of the above that have jeopardised economic stability, national survival and preservation of culture. Some of the examples that come to mind for me straight away are: IMF in Bolivia, and one that is more recent which is more vague is the the TNCs that operate in Australia that are not produced here, such as Volkswagen which in short terms, was the reason that Holden is now going out of business, which is a 'loss of Australian culture.'
The second is obviously weaker but this is just a quick example to get you running!
