Please

  1. We can't see your code; post it using code tags as described in How to get the best out of this forum.
  2. We don't know which board you're using.
  3. Screenshots of error messages are useles; there should be a button "copy error messages" at the right of the orange bar. Use that to copy your error and past it here (again using code tags).

Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advise on) your project :wink: See About the Installation & Troubleshooting category.

See that [] in your code here on the forum? That's why you were asked to post using code tags; please read How to get the best out of this forum and please fix your previous post #3.

The multiple ".h" files refer to redundant entries, for example;

.../BlynkTimer.h:36:21: 
error: redefinition of 'class BlynkTimer'

Look through your .h files (or comment-out one .h entirely) to find the redundancy and re-compile.

Format your code in your post like this (I will remove this code block after you tidy-up your post):

#define BLYNK_PRINT Serial

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
