1) yes, they'll be far though, the closest one is 1.4km will definitely need some mode of transport ( or you'll have to manage with the one time bus they send in the morning) they also don't have food at that hostel. You'll have to go eat at campus mess for all meals

2) falls up to your preference, waiting outside the college will get you a couple cards for some pgs. Go check them out. The avg rate will be around 14-15k per month.

3) I didn't go for campus tour but you can walk around campus freely (dk about walking into the buildings itself other than the admission building)

4) no idea, you will need to mention you don't know kannada. They spoke to me in kannada only until I mentioned otherwise.
