Can your spirits or spells harm me?

Mostly No.
Spirits do not harm people, people harm people.  Some negative entities can make you weak, vulnerable or create chaos, the harm happens when you do not take the right actions and act in time to correct it.
Yaya Maria works with responsible spirits and her spirits will never harm you, they will protect you from harm, the same way they protect Yaya Maria.
