I realize now why these sounded so familiar, they're from Assassin's Creed (I've inquired about a tune from those games on here before).

Specifically Assassin's Creed Unity. All three of these tunes are played by the street bands found in various corners around Paris.

In this video, tune 2 is heard at 14:00, tune 3 at 14:45, and tune 1 at 15:57. Afterwards, all three tunes just continue to loop until the end of the video.

According to the game's credits, Seán Dagher was the one playing the hurdy-gurdy on these tunes. Seán is still quite active on social media so perhaps contacting him might be the best way to identify these tunes.
