If you’re variables are named like above you could loop through them with a for() loop and take advantage of the $i incrementor:

function displayprice() {

	$return		= '';
	
	for( $i = 1; $i <= 3; $i++ ) {
		
		$price = get_field( "price{$i}" );	// price1, price2, price3
		$link  = get_field( "link{$i}" );	// link1, link2, link3
		$return .= sprintf(
			'<a href="%1$s" class="%2$s">%3$s</a>',
			esc_url( $link ),
			"price{$i}",
			$price
		);
		
	}
	
	if( empty( $return ) ) {
		$return = __( 'Not Available' );
	}

	return $return;
	
}
add_shortcode( 'showprices', 'displayprice' );
