Answer 1

Please change :

List<Account> acct = new List<Account>

to

List<Account> accts = new List<Account>();

Answer 2

I want to help you to understand how programming works:

Apex is similar to Java (a programming language from oracle). Each instruction should be closed by a semicolon. ;. In order to call a method use brackets () inside of these you can send parameters to your method.

The issue in your case was caused by missing brackets and semicolon.

List<Account> accts = new List<Account>();

List<Account> indicates that you want to declare a variable. You variable is called accts. The variable is initialized (=) by a method called new List<Account>(). It creates a new object from type List.

trigger CustomerTrigger on Customer__c (before insert){
    List<Account> accts = new List<Account>();
         for (Customer__c newCustomerRecord: Trigger.new) {  
            //Check if the Customer belongs to a Key Account
            if(newCustomerRecord.Key_Account__c!=Null)
            {
                Account ac=new Account();
                ac.Name= newCustomerRecord.Name;
                ac.BillingStreet= newCustomerRecord.Customer_Street__c;
                ac.BillingCity=newCustomerRecord.Customer_City__c;
                ac.BillingCountry=newCustomerRecord.Customer_Country__c;
                accts.add(ac);
            }
      }  
    insert accts;
}

First of all,
I think you have not noticed that there is no such field on account object like Customer_Name_c and Customer_Address_c (that’s why this error occurred “Invalid field Customer_Name_c for SObject Account “). So you have to create these custom field in Account to map with customer object or you should use standard fields of account object. And one other point that you can’t map address field directly. So you should use these account fields(BillingCity,BillingStreet).
