You are buying one potted plant. Potted plants are much better to start with as they have their entire root system intact and makes it much better when transplanting.
Potted plants are started in rock wool. To plant remove as much rock wool as possible. Most of the rock wool will pull off. If you have any left and want it off shake the plants in water gently by holding it by the stems and leaves. Leaving some rock wool will help anchor the plant in your substrate.
To separate the plant into individual plants grab the stems right above the root and pull gently. The roots should separate if they don't stop pulling and try other stems. Swirling this plant in water will help each plant separate easier.
Plant only plant the root in your substrate, not any of the plant itself or this can cause melting or shock, for more information on planting and care for your plants, please go here
