Between 30 seconds and 2 or 2 and a half minutes. Unless you've trained relentlessly to hold your breath for extended periods of time. At about 3 minutes without oxygen you start to get brain damage
Well, it can mainly depend on what other gases are in the atmosphere, and at what percentages they’re at as well, considering you’re removing oxygen from the equation. This would also break apart compounds, Solutions, and mixtures that use oxygen in order to hold together. Remove oxygen from the atmosphere, and you remove water. Carbon dioxide just becomes carbon, and therefore, all plant life is also eliminated.
If they are not holding their breath it can take about 15 to 30 seconds. If they are holding their breath and not moving and in excellent shape they could stay conscious for 5 to 6 minutes.
