It all depends on the tyres and should have the pressures on the sidewalls, 50 sounds OK.

50+ psi is road bike pressure, I would run my downhill bike on 20/30

If they feel soft then they probably are...

That's OK if you have some way of preventing pinch-flats plus it depends on the tyres, mine (VelociRaptors) have blocks that flex front to back and are rigid side to side but they need to be 60psi to work properly.

My road tyres are 65psi (they're continentals - don't ya know!)
And my ****bly tyres are 35-40 depending on what riding i'm doing.
