What are the 5 examples of derivatives?

Could you kindly provide me with five illustrative examples of derivatives? I'm particularly interested in understanding the diversity of these financial instruments and how they operate within the broader financial ecosystem. Could you explain the characteristics of each example, highlighting their unique features and the risks associated with trading in them? Additionally, would you also elaborate on the role derivatives play in hedging risks and facilitating more efficient capital allocation? Your insights would be greatly appreciated as I'm eager to deepen my understanding of this fascinating area of finance.
