Hi,

you can try this..

first get all the user ids from the lookup field
then query all the user fields based on the ids
finally update the name field

trigger pudatename on BuyAirtime__c (before insert, before update) {

Set<Id> mentorIds = new Set<Id>();

for(BuyAirtime__c  ba: trigger.new)
{
  mentorIds.add(ba.Mentor__c);
}

Map<Id,user> userMap = new Map<Id,User>([select id,name from user where id=:mentorIds]);

for(BuyAirtime__c  ba: trigger.new)
{
  User us = userMap.get(ba.Mentor__c);
  ba.Name = us.name +' '+ ((ba.Buy_Airtime_Date__c).day()+'/'+(ba.Buy_Airtime_Date__c).month()+'/'+(ba.Buy_Airtime_Date__c).year());
}

}

Since the User record is related to the Buy_Airtime record, you should be able to just run a query for all of the records in trigger.new, but accessing the related user fields that you need.

List<BuyAirtime__c> buyAirtimes = [SELECT Id, Mentor__r.Name, Buy_Airtime_Date__c FROM Buy_Airtime__c WHERE Id IN trigger.newMap.keySet()];
for (Buy_Airtime__c ba : buyAirtimes) {
    ba.Name = ba.Mentor__r.Name +' '+ ((ba.Buy_Airtime_Date__c).day()+'/'+(ba.Buy_Airtime_Date__c).month()+'/'+(ba.Buy_Airtime_Date__c).year());
}
