Come on... These aren't that hard. I'll do two of them for you but the others you need to go too google and type in 'define: _______'. Otherwise you won't learn anything!
Multinational Corporations: Multinational Corporations are business orginisations which have their headquarters in one country, but operate in a number of other subsidiary states. MNCs are a vital element of globalisation as they directly contribute to multi-lateral trade, employment and labour, capital and the goods or services they produce are usually also mobile.
Internationalism: Internationalism refers to the concept that a common humanity exists beyond state, cultural or other boundaries. Internationalists often promote a 'universal good' which is non-discriminatory and applicable to all cultures, countries and people. This 'universal good' is comprised of ideals such as universal human rights and equity amongst countries and people.
NOW DO THE REST YOURSELF! It's no good to use someone else's definitions anyway. You will be able to remember your own much better than mine.
