NWN uses a set number of 2da files for determining some of the game's settings. There is a finite list of what 2da files get used and their usage depends on their name. So, for example, when the game loads, it will look for baseitems.2da (first in its own data, and then again if baseitems.2da is present in a hak that will override the game's standard data). If a 2da is called "baseitems_custom.2da" it will be ignored along with its content. On the other hand, all versions of the file named "baseitems.2da" will be included, one after the other depending on hak order (the latest overrides the previous ones completely at each step).
The way 2da files are structured is very primitive in appearance: it's a series of lines and columns and the network of the game references these lines to get the data in the columns. So if you have two haks that use the same 2da file (but with different content), only the latest one the game scans before starting up will be included and have its content rendered to the game.
So to answer your question: if the haks from different sources you want to include contain the same 2da file, they will need to be merged (made so their line entries do not conflict) and placed in the topmost hak in order to take effect. If one hak contains 2da files that are not in the other, then they aren't under a different name - they simply aren't in the other hak and you don't have to do anything to them.
