Perfectly normal. Engine and battery drains. Ride on...

Edit, I have two hoses... could be wrong on the "engine" drain. Radiator/fuel? They are normal though.

 

Weird I didn't notice it before. Thank you for the info!

 

Could have sworn that was the fuel cap run off.

 

Various vent hoses. You should not be worried.

 

Yup. Typically the fuel fill overflow, fuel vent, coolant overflow.

 

Fuel overflow and/or coolant overflow. There are two on my '21; same on the older gens I think. Only be worried if is clogged or there's fluid running out of it constantly.
