Not - papaya.
Mangos don't grow in groups (despite the inflorescence being a dense panicle) and don't grow in the trunk. Besides that, the leaves of both trees are the most different leaves that you can imagine - mango has simple, lanceolated, normal-sized, hanging leaves on short petioles, papaya has giant palmatolobate leaves with very long petioles and held horizontal. (See mi photo of a papaya recently uploaded in Artis zoo, inside the bird house)
