All these planets are naked eye objects, and except for Mercury, are easy to see. Venus is also part of this grouping, Meaning that all 5 planets known to ancient astronomers are on the same side of the Earth. (and the sun is on the other)
The planets are not exactly "aligned", just they are all visible in the sky, spread over a wide part of the south eastern sky, a little while before dawn.
Sky and Telescope has some nice guides to what you can expect. Mercury is always the hardest, as it is always in the twilight. Saturn is an easy sight, appearing as a slightly yellow star. Binoculars will show its moon, Titan.
Best time is around the first week of Feb about 45 min before dawn.
