Hmm, what makes you think that only Kaguya can create them? She was the only one shown creating them and Minato explained that they cant be created. Madara, Naruto, and Obito didnt create more when they lost any of them which would have GREATLY helped them in their battles.

Hagoromo and Hamura are shown with different numbers of TSB - originally they had one sphere, but later they increased in number, Hagoromo has 10, Hamura has 9. Not sure how you came to that conclusion. They were never shown with 1.

Obito also created them, which we were shown when they first appeared. No he didnt create them. They were inactive. Only after gaining full control of the Juubi could he summon/manifest/activate the other 8
