So far, up until chapter 92
We were revealed all 9 titan shifters. The manga showed two more, Jaw and Cart, which were the missing two. I will not say who is whom, but to answer your question, yes, only the ones you mentioned are shifters within the troops of 104th squad.
However, in the latest chapter (93)
We are revealed that Ymir is indeed the Jaw titan, thus we only know 8 shifters.
To answer your question
Yes, as far as we know, no other titan shifters are present in the members of 104th corps.
But, according to some fan-based theories
there might be one type of titan shifter among the 104th. But I will not speculate. here
