Narrative:

Mechanic Y and I were taxing a crj-900 aircraft from the hangar to the gate. Mechanic Y was in the left seat in control of the aircraft; I was sitting right seat running radios. We completed the checklist per company run/taxi book prior to starting to taxi. I called [gate control] to initiate taxi then switched to ground control 121.9 as directed. Once listening to ground; we were told to hold short of 35. Before I called back; he amended those instructions and said turn left on lima to november; hold short of 35. We were then told to change frequencies to 126.7 while holding at 35. We had radios with 126.7 on comm-1 and 123.67 on comm-2. While waiting; ATC [ground control] called with instructions; I was late repeating and ATC instructed us to wait before I could call back. When he called back he instructed taxi 4; hold short 35. Mechanic Y called back 'taxi [runway] 4; hold short 30-right'. ATC did not call back with a correction. We looked left and right; no planes were on approach. We called 'clear left'; 'clear right' and taxied across 35 on november; turned left on 4 and taxied to 30-right where we held short. We then continued to the gate as instructed. When we got to taxiway quebec; almost to the gate; ATC called with a phone number to call the tower who told us of the incident. I miss-typed; it should read 30-left instead of 30-right. ATC started with us taking one route to the gate; he then changed the route which confused us and ATC. ATC thought we were on runway 4; but they had sent us on november. While waiting to cross runway 35; we changed frequencies; the misinformation was somehow passed between ground controllers. Since I am new to taxiing; I was not as fast to respond to ATC which caused confusion when he told us to wait; instead of letting me call back as normal. Mechanic Y called ATC back; [to verify] we get told to wait again; when he; mechanic Y; had called back with incorrect directions [to ATC]; ATC should have listened and corrected him. It also would make no sense to be told to taxi and hold short of a runway we were already holding short of. When we gave the incorrect callback [to ATC] we should have been notified right away. Slowing down of communications and speaking clearly so both parties can understand.
