Does it mean that all life has a specific set of DNA encoding their biology?
In other words every type of species has specific DNA which is UNIQUE FOR THEIR species?

Yes, and yes.
While since each individual, regardless of species, has it's own unique genetic makeup, you could say that each individual has it's own unique genome, BUT
In general, when the term genome is used, as in human genome, it refers to the genetic makeup of all humans. And so for example, there might be a 100 alleles for some genetic loci, but an individual would likely only have 1 or 2 of them. Other individuals in the population would have different alleles, and overall amongst all the individuals in the population, all 100 alleles could be found.
The human genome would be a documentation of all the possible alleles, even though all of them wouldn't appear in every individual.
