research.rooms is an array, so to get access for each room in this array- you have to loop throw it.

For example:

research.rooms.map( room => alert(room.adultcount));

Or, in older js syntax:

for(var i = 0; i < research.rooms.length; i++){
    alert(research.rooms[i].adultcount);
}

use index to consume array property research.rooms[0].adultcount,

$( document ).ready(function() {
var research=  {
  "city":"1186432",
   "hotelname":"OKHTINSKAYA",
   "indate":"2017-12-23",
   "outedate":"2017-12-30",
   "rooms":[
      {
         "adultcount":"1",
         "childcount":"1,1"
      },
      {
         "adultcount":"1",
         "childcountandage":"0 "
      }
   ]
}
var re = research.rooms[0].adultcount
alert(re);
});
