Any 747 model is capable of maintaining altitude up to about 27,000 feet at 90 percent of Maximum Takeoff Weight on any two engines. At lower weights, it can gain altitude. The problem with any multi-engine airplane is that whatever caused the dead engine to die is also likely to get the remaining engine(s) before too long. So any engine-out situation is a critical situation. But a 747 flies about as well on 2 engines as (let's say) a Piper Aztec flies on one engine. Have an enjoyable flight!
