Answer 1

try to start mongod with admin option as it is not able to open the file mongod.lock

Answer 2

You can't start multiple MongoDB processes on the same database.
What you need to do is:
mongod --dbpath c:\database1 --port 27017
mongod --dbpath c:\database2 --port 27018
Remember that you must manually create the database folders.
Usually if you read carefully the error log you will find the problem:
"13627 Unable to create/open lock file: \data\db\mongod.lock.
Is a mongod instance already running?"
