It is possible to use multiple I²C devices, all is needed is for each one to have a different address and the ability to set up the wiring(the other answerother answer points to wriring info).

Of the sensors you listed only one is an I2C device(Grove sensor).

The DHT11 uses a single digital wire to communicate and the air pressure sensor is an analog device. Although you do mention having several devices, the only thing you need to be sure of is if there are no address conflicts, i.e. there being two devices with the same address on the I²C bus.

If address conflicts are an issue most devices provide a way of changing that address, often there are solder jumpers on the board. This allows you to change a devices address to a unique one.
