On some users below the rep bar I see message as 1 alert etc. What are those ?
Apart from warns, you may also recive an alert. An alert is a mild form of warn. It does not have any warning points associated with it. But you will have a message in your postbit in red for 2 days once you have been alerted. The reason for the alert will be communicated via pm.
Taken from the warning system basics here

Like for me,
I got an alert coz’ I was abt to start a flame war in the Ferrari vs others war before the European GP.
I wrote a very impassioned speech abt people who keep criticizing Ferrari. Both when they are at the top and when they are losing

Alerts are implemented for better moderation.
It helps the staff recognise the members who have already been alerted once.
This information is available to all the mods/gmods/site managers/Admins and Ring members…encouraging better cooperation amongst the staff.
Alerts are like a normal PM a mod or staff member would send you incase you violated some rule of the forum.
An Alert is not a warning, will not increase warn points, and is not a ban…over a section or any other normally accessible part of a forum for the member.
Why am I not alerted? I have done something in the past 
i wud hav done dat to u there oh yeah 
and the warning kinda stuff is when u go out ur boundries and
got it to freekill
