Of course! Your friends and family can stay with you during the preparation phase and they can follow you almost next to the boarding area. They can then wait for you outside and watch you perform your jump from the ground.

The tandem instructor will indicate the parachute color so they can recognize you when the parachute opens. 

After landing, they will be able to see your emotions and you will be able to share the experience with them. 
There are great chances that they will join you in the aircraft and jump as well next time! :-)
