In this case, can we use both "already" and "3 times" in the same sentence? Yes.
"I've already been there 3 times".
Could we also say: "I've already been there many times"? Yes. Both sentences are fine but do not have the same meaning. The first sentence tells the number of times while the second sentence describes an indefinite number.
Thank you

Ps: is both at the right place in my question? Yes.
