Can someone explain to me how can i identify the novel genes in my set of gene of non-model organism ? is the novel gene ,the sequences which does not match similarity with other organism when functional annotation run ?? So all sequences with no BLAST results are novels??

That is pretty much the basics of it. First you would have to do some sort of gene prediction on your non-model organism genome - but I guess you have done that as you say you have a gene set. Then of those genes, the "novel" ones are those that cannot be mapped with confidence to existing entries in any public sequence database - so certainly those with no BLAST hits., but even if a gene had a BLAST hit, it may be pretty a poor match.

Genes annotated as hypothetical proteins usually do not have close homologs and hence novel?
