mackjack , Do you want to put them in a single output message or is it good enough to print them in multiple messages?

For the latter you can use a for()-loop and have a look to the functions lr_paramarr_len() and lr_paramarr_idx().

should print in multiple line from same output message should also be ok.

and if i need to print in single output message how can do this possible ?

It is good to invest in some basic C programming skills. But here is how you might solve this.
Put this code before of you vuser_init() function.

int my_paramarr_out_message(char *prefix, char *sep, char * postfix, char *param_name, int value_str_len)
/*
	Prints a list of all values of an array parameter with some formatting to function lr_output_message().
	A temorary buffer is allocated to contain the message. This buffer is enlarged when the estimated
	initial size is too small.
 	Arguments:
		prefix: The string that is printed at the beginning of message
		sep: The string that is printed between the array elements.
		postfix: The string is is printed at the end of the message.
		param_name: the name of the LR array parameter
		value_str_len: An estimate of the average length of the array parameter values.
	Returns:
		The length of the printed message.
	Examle:
		my_paramarr_out_message("Array values of TEST are: ", ", ", ".", "TEST", 10);
	Todo:
		Argument value validation (e.g. null-pointers or values < 0)

{
	char *buf, *p, *s;
	int buf_len, params, offset, idx;
	
	buf_len = strlen(prefix) + ( strlen(sep) + value_str_len ) * lr_paramarr_len(param_name) + strlen(postfix) +1;
	buf = (char*)malloc(buf_len);
	offset = 0;
	params = lr_paramarr_len(param_name);
	offset += sprintf(buf+offset, "%s", prefix);
	s = sep;
	for(idx=1; idx<=params; idx++) {
		p = lr_paramarr_idx(param_name, idx);
		if( idx == params ) s = postfix;
		while(offset+strlen(p)+strlen(s) >= buf_len) {
			// We have estimated the buffer too small: add 25%
			buf_len += 1 + buf_len>>2;
			buf = (char*)realloc(buf, buf_len);
		}
		offset += sprintf(buf+offset, "%s%s", p, s);
	}
	lr_output_message(buf);
	free(buf);
	return offset;
