In episode 26 A boy falls on top of a girl and they blush. But nothing else happens.

None, but the characters do fight with magical wands, punch and kick at monsters.

The words Damn, Dammit, and I believe Hell is used commonly.

The villains are seen drinking bright colored drinks out of cups that look like cocktail cups. It's not certain what it is.

Bel smokes a cigar commonly.

None, except the monsters could be thought "scary".
