Donating to a support organization is a great idea and an excellent use of your money to support many people.On a one-to-one basis, you can also support orphans that are refugees by applying to bring them to the U.S. (not always doable and not always a real orphan).  Alternatively, many refugees are in the U.S., but wanting to bring family members that are refugees:  in those cases some refugees do not have money to do the financial sponsorship for their family members or pay the legal costs to apply to bring their family to the U.S., in those cases assisting with legal fees or helping with an I-864 (WARNING: Major risks involved, be sure to consult an attorney so you fully understand what you are getting into) may be of benefit on a one-on-one basis.Note, as Annika Schauer stated, a refugee application does not need an affidavit of support / I-864.  However, sometimes a refugee wants to bring a family member that does not qualify or the person missed the window to sponsor a family member as a refugee, and as a result needs to do a standard petition and show financial sponsorship.
