The nitrite and nitrate at "0" (I'm assuming this is what you mean by both being fine) inidcates the tank is not cycled. The ammonia at 1 is the first stage; it will drop down to "0" and during the drop the nitrite will rise and then drop to "0", and during that drop the nitrates will rise [simplification, but you get the idea]. All this takes from 2 to 8 weeks, and that depends upon other factors.
The guppies will maintain the ammonia, and the bacteria will appear and do their work as outlined above. Patience is a virtue in this, to avoid fish loss.
You can assist the process a bit by seeding the tank with bacteria from another well established (cycled) tank [such as the filter media], and by using a product like Stability or Cycle. But the biological cycle still has to establish itself. When you have readings of "0" for ammonia and nitrite for several consecutive days, the tank is cycled for the bioload it contains at that time. Then you can add fish, slowly at first to avoid crashing the cycle; in a 10g I would only add 2 or 3 fish, wait a few days, then again--again, this only when the tank is cycled.
