It does happen fast at this time of year. Short answer: yes, he should definitely ask the coach what their level of interest is. Not to derail any other answers you might get, but you might find the following recent thread helpful:

Things to think about:
- are they all asking for academic info to do pre-reads? Don't pay money to travel anywhere unless this has been done first.
- get your son to clarify what each coach is offering. If these are very selective schools, does "they are very interested and want him" mean that they will give him a slot with admissions (i.e. almost guaranteed admission)? put him on their high priority list, but with no guarantee? are they telling him if he gets in he could play? these all mean different things.
- is he interested in the school with the camp? in the end he can only attend one school, if he has other options he is more interested in pursuing, then go with those first.
- definitely visit those he is most interested in, if you can manage it, that's the only way he will get a feel for the school and the baseball program. There are a limited number of weekends before October, so he has to prioritize.
