Redundancy help PLEASE!!!!

I have recently been told that I could be made redundant.
The Query I have is that the redundancy briefing I had and forms I was given state a different job title to my contract job title...

1. Is this OK?
2. If my job title was stated correctly on the redundancy forms I recieved, does that mean everybody with that job title should be told they could be made redundant?
3. Does length of service have any bearing?
4> Can you help???

Sorry...1 more Question..

Should redundancy be offered to people with the same job title as me if they want their redundancy instead of just picking who they want???

THANX
