The item for the first guy is dropped by  エレメントマスター at Handa's competition route :3

For the second one, its dropped by  ニヒルヤリーズ at Kusaka's friend competition route

For the third one, its dropped by ヘアークリップス also at  Kusaka's friend competition route :3

Don't know about the forth one ( Says something about being dropped by Legend 2 Team )

The last one is dropped by Aqua Hermit (One of the Granfather Route teams, don't know where it is though)

Hope this helps Pedro! :3
