Narrative:

Operating a flight in an MD90 from ZZZ-slc. We were level in cruise flight of FL310 over central colorado when we received indications for single elevator feel fault, stall indicator failure, no hydraulic pressure or quantity for the right hydraulic system and failure of the autoplt. The captain hand flew the aircraft as the autoplt would not re-engage and I completed the procedures for stall indicator failure followed by the single feel fault. We both idented there was no hydraulic pressure or quantity in the right system and I completed the procedure for right hydraulic system failure. I then contacted dispatch and maintenance via radio and detailed our indications. They agreed with our assessment of the situation. We advised dispatch that we would declare an emergency and continue to slc. The captain declared an emergency and stated our intentions with ATC. The captain briefed the flight attendants of our situation and had them prepare for an emergency landing. We completed the remainder of the normal checklists in addition to the alternate gear extension procedure from the right hydraulic system failure checklist. The WX was VFR and we received vectors for a hand flown ILS runway 34L approach with emergency equipment standing by. After a soft touchdown landing, we stopped straight ahead on the runway and completed the 'prior to taxiing' section of the right hydraulic system failure checklist. Maintenance safely pinned our landing gear and we were towed to the gate where we made a logbook entry. The captain contacted the chief pilot and our dispatcher. The flight attendants did an excellent job and all passenger exited the aircraft in good spirits with several statements of job well done.
