Answer 1

You could try to use

su - username

in order to switch to the user you want.

You can find more documentation about su command here

Answer 2

You can provide the password to sudo like this:

echo "p@sw0rd" | sudo -S cal -y 2011

The example above runs 'cal -y 2011' with root permissions.
