<1> is an alias for <me>, so you can skip that one.
It might be helpful to go in order of healer-tank-raisers-nonraisers. So if your party list is you-healer-tank-tank-DDs, the order should be <mo> <t> <2> <3> <4> <8> <7> <6> <5> (the DDs are in reverse order because RDM and SMN are at the bottom if you're using the default sorting). This creates a macro that does a great job of raising anyone without having to target them if only one person is down, and will do a fair job of raising "probably the right person" if you press it without changing targets while multiple people are down. And if you want to be sure, you can mouseover or target. If you've changed your sort order, you'll need to change this order a bit.
