It probably depends on the airline, but the one I worked for a few decades ago would not consider this to be a cancellation. The flight needs to be 'completed' for internal bookkeeping reasons. The 'different' flight number is probably required by ATC (but an expert in that field hopefully can clarify)
Q2. What is the actual arrival time of an aircraft? Is it touchdown or arrival at gate or when the doors are opened and PAX disembark? What constitutes arrival time?
Again it depends on the airline, and could differ depending on the purpose. Normally a flight's schedule is block-to-block.
In the sense of Regulation 261/2004 your flight was not cancelled as the regulation defines cancellation (Article 2 (i) as:
‘cancellation’ means the non-operation of a flight which was previously planned and on which at least one place was reserved.
Does Emirates define 'cancellation' in their terms and conditions? If they do, that text forms part of your contract with them.
