In games like this, you should be trying to make stronger hands than one pair. To that end, look more favorably on hands like A3s than AJo, or 88 rather than KQo. You want hands where you will either hit your hand on the flop (ie a set) or flop a good draw (ie, nut flush draw). In those cases, you'll be loving having 5-6 people in with you. You play an AK and flop a K, you're going to have to play extremely well to make this +EV (and from the tone of your post, you don't sound like a very experienced player capable of this).
