As Follows:
#1 was for delegating 1000+ sgb during epoch (week)- "Final Adjustments".
#2- Next was for delegating through epochs 3-6, with 500/5000/50000/500K delegated (tiered rewards, the higher you went, you got one for each tier you were at or below). I only got the bottom tier one since I didn't have that much. "Signal provider since 1859"
#3- The next was for continued delegation of [some amount] during epochs 3 and 4 when their node was interrupted. This one gives an extra NFTp per day I believe. "H.P. Booster" (Hugo Philion, CEO of Flare Finance)
#4- Last is a collaboration between Best FTSO and NFT Riddler. It is a Whitelist NFT, which will allow us to buy a Generator NFT in December for a steeply discounted price in SGB (unknown at this time) which will then be used to generate a 1/1 unique Bored Apes NFT on Songbird in Q1 of 2022. "Bored Apes XRP Utility Fork NFT" (or something like that).
All are sellable on best FTSO's website bestftso.xyz, and some are going for some crazy amounts of songbird (10K, 20K, etc.)
And there is much more to come. They are both also involved with Kings of Strategy, a new game starting up soon on Songbird network and eventually on Flare network in main grander scale.
