Narrative:
On takeoff (first officer flying) the landing gear failed to retract as a result of [landing gear control interface unit] lgciu 2 failure; at which point we cycled to gear to get a successful retraction. During the climb-out we then had multiple failures to include engine 2 reverser fault; anti-ice captain aoa fault ecams; as well as indications on the first officer pfd that the aircraft air/ground sensor believed the aircraft was still on the ground. At this point we continued to work the failures and coordinate for an emergency return to the departure airport. After declaring an emergency with ATC we returned without incident for a normal landing; the captain now flying. After landing we then had a landing gear system disagree ECAM fault; and were able to taxi to the gate without incident.
