Are these blue wisps near the polar cap of Mars, clouds?

That’s a good observation.

Yes, these are clouds. Martian polar caps have frozen CO₂ which give rise to Cirrus clouds when exposed to the sun. In fact, these cirrus clouds(the thin, wispy, high altitude clouds that we see on Earth) are also present on Jupiter, Saturn, Uranus, Neptune and even on Titan.
