Other notes:
You have an option for which set of generals to fight this time, so choose whichever you prefer. If one of your targets get killed by your other forces, you have a backup strat rather than having to reset. Either way, this will be a bit of a tough fight, since you have to learn to deal with Meng Huo's low movement speed and slow attack speed.
There is also an alternate win condition which I demonstrate here, rather than having to fight Zhuge Liang, you can kill off all the other generals within 30 minutes and he will retreat instead. You may have to lower his morale enough in this time, but make sure he's the only one standing on the Shu side.
As for the 4th weapon conditions, Zhang Fei's group starts in the north west, and Ma Chao's group in the far east corridor. Making liberal use of Meng Huo's Musou attack should give you an easier time of making sure you get the kill on the target generals rather than anyone else. His Charge 6 gives you a nice amount of crowd control too, and both attacks have impressive range on the ground to keep a large amount of troops down.
