religions and buddhist mala bracelet

I have a buddhist mala bracelet i got from a chinese buddhist temple because my grandmas follow buddhism (and taoism). ive been thinking about religion, researching religions, like multiple, not just buddhist and have been kind of converting to multiple. specifically christianity, buddhism, and taoism/daoism. basically - ive started to kind of believe in god/gods. Is it okay for me to believe in multiple religions?
also about that mala bracelet, ive been using it as a hair tie occasionally and im not sure if it’s disrespectful. my sister said that buddha would find it resourceful lmao but i want to know if its not okay to do.
basically my questions:
is it okay for me to believe in multiple religions?
is it okay for me to use a mala bracelet as a hairtie?
