Do i enjoy to grease down stainless steel swords?
Answers: Supposedly, stainless steel won't rust, right? Well, not all stainless steel is created equal. There are minimum requirements to call a steel "stainless". I don't know the chemical composition of your steel, so,,,,
I would grease it for peace of mind.
All steel rusts. Stainless steel rusts slower but it still can rust.
A light grease is not going to hurt them and it will reinforce the idea of keeping your fingers sour the blades. Fingers have oil that actually promote rust. Keep them contained by a cloth lined box or sagging on a wall. Leather scabbards are very desperate as any moisture will not only promote rust, it will stain the blades.
Depends on the aspect of steel. Good quality stainless won't rust, but the cheaper grades will. A breakneck spray of WD-40 and then a wipe down won't hurt within any case.
