i have some questions about pugs!??

Hi, im looking into getting a pug,i have done my fair share of research and think they are great even with some of the illnesses they can get.
I go to college for 2 and a half days for about 5 hours, I have an hours break and I live about 5 minutes from the college, so I could drive home from college to play with him etc and my mum stays at home like all day most days, sometimes she goes out with friends. also we have another dog, hes a Labrador, he so friendly and playful, absolutely loves other dogs.

I have some questions that I couldn't get answer for on the internet
are they good with kids?
how much do they eat? like a proper diet
how much walking do they need?
would it be okai to walk the pug with my own dog?
if I let it sleep on my bed, and I accidently kicked it while I was asleep am I likely to kill it or is it likely to kill me? or am I better keeping it off beds and chairs etc?
can I let it off the lead over the field? I don't want to let it off and it hurts his eyes poor soul
are they okai going to a kennels if I go on holiday?
do they chew things? if I bought him toys, is he less likely to want to chew my shoes up?
does your pug get half the things they say about on websites like eye ulcers, skin problems etc. im never sure whether I should believe what they say on the internet.
are they good moving dogs? like if I move out, would he be okai with it?
can they live in apartments?
do they bark loud?
is there anything at all I need to know?
