In stop-and-wait ARQ why shoukld the receiver always send an acknowledgement message each time it receives a frame with a wrong number sequence?

When the receiver receives a good data packet, it sends an acknowledgement packet to the transmittor with a sexquence number of the NEXT packet it expects. That means, if the člast received data block has a sequence number 0, then the ACK contains sequence number 1, because the next block the receiver expects, ought to contain seq. number 1.

What is the relation between the window size ad sequence number?

window size is actually the number of frames that can be sent without acknowledgement in sliding window protocol and the sequence numbers are produced for these frames. For example if window size is 4 then sequence numbers produced will be 0-4, where 0 - for first frame, 1 - for second frame, 2 - for third frame , 3 - for the last i.e fourth frame, and seq number 4 is for acknowledgment of the 4 framed relayed.
