Hello Friends, I need your opinions about my 2 Oxydoras Kneri, Do you think that they can be of different sexes?

Niger Catfish male and female?

We appear to know very little about kneri. Very few people get to keep them whilst they are of much more manageable size than their cousin niger.
But Oxydoras niger is well known and there AFAIK sexing them reliably is unknown. See the sexing section on PCF:

I have five O. niger 30"-36" in a 4500 gal and I only guess that the four plum ones are females and a somewhat more streamlined one is a male. I've not tried to look at their ventral shots.
