You can use a fan splitter, for example: https://www.amazon.ca/Phanteks-3-Pin-Y-Splitter-Cable-PH-CB-Y3P/dp/B00M0R9BV0

A motherboard header (SYS_FAN) typically has a max. rating of 1A. So, check the ampere draw of the fans you will connect (it can be seen in the back of the fan with the sticker label). For safety, you want that all fans connected to a header will only reach 75% of the header's rating (which is 0.75A). You can safely plug in 2, 3, or more fans as long as you keep the total amp draw of all fans within that range.
