Answer 1

I advise you to start sololearn's Java course, that's no doubt, you're not aware of it
Variable declaration is one of the first things to learn.

float a=1,n,s=0;
Here is missing the name of the variable that will be assigned the value 1.
Better name it a, to fix your loop error

Answer 2

I don't know what you expecting through this program first mistake is in variable declaration u assigned 1 to float here variable is missing then inside loop u used if condition your condition will be failing for positive Integers

Answer 3

See this one
import java.util.Scanner;
public class Main
{
public static void main(String[] args)
{
Scanner in=new Scanner(System.in);
float a=1,n,s=0;
n=in.nextFloat();
System.out.println();
while(a<=5)
{
if(n<0)
s=s+n;
if(n>0)
s=s+n;
a++;
}
System.out.println(" %.2f "+s);
}
}

Note : first do always dry run this a good practice how your program flowing and try to solve your errors self read them properly and try to fix it one by one
