2. I think it is 1002
4. Clients are numbered by the order in which they come (i.e die)
5. What happens if someone comes to visit a client and his grave has
already been emptied (like in the example i suppose, since clients 2
and 3 must have already been 'evacuated' if the correct output is
really 3) ?

I think that when it sais
500 v 2
1003 v 3
1236 v 2
2032 v 2
in example it refers to the grave number 2 , respectively 3.
Otherwise it doesn't make sense.In the problem is said that after
1000 days the friends and relatifs forget where the grave is(so why
would they come to visit again).In this case the answer is realy 3.
1 d
1 d
1 d
1 d
300 d->to the crematory
500 v 2
1001 d
1002 d
1002 d
1003 v 3
1003 d->to the crematory
1003 d->to the crematory
1236 v 2
2032 v 2
2033 d
For example why isn't there last client(time=2033) in the crematorium? His neighbour 2 is visited at time=2032 (one day earlier).

In the text it clearly states that the number is the number of the
client (not the grave or whatever)
So it's weird
Anyway in the example 2032 v 2 makes 2033 d go to the crematory
(unless 2 is really client 2 and his grave was emptied and they
don't visit anyone, just walk around the cemetery and can't remember
where their departed friend is buried and they go home like morons).
