No, you can’t copy/paste keys, but if the only difference in the emitters is the time at which they happen, you can set the first one up then COPY it, then move to the time you want the second to happen and PASTE, move to the time you want the third to happen and PASTE, etc.
The only other thing you can do is get the first life graph setup the way you want it, then r-click in the graph and set it as a reference graph.
