Why are you looking for an "easy" language to learn? I don't know if there is such a thing. Of course, I agree that some languages are easier than others depending on your native language however I think everyone will encounter challenges when learning a new language (or any skill for that matter). If you do not have a strong enough motivation to learn the language then I am afraid you will always quit when it gets "hard" or you encounter any challenges. If you have a strong enough motivation to learn the language then you will have the fortitude to persevere when things get tough.

I hope you are able to find a language that you are passionate about.

Good luck.

Arabic, turkish, hindi, urdu, farsi and English are kind of connected to each other..there are so many turkish, urdu and farsi words  originated from the arabic language...hindi and english are too close coz both are derived form the  Sanskrit language...

I recommand that u go for hindi and later for urdu...for both languages are easy and very connected to each other...while learning hindi u will find many vocabulary drawned from turkish and English and that will makes it easy and fast.. :)

Portuguese is a beautiful language :)

If you want only an easy option, then you'll find everything too hard.

It's better to just ask yourself why you even want to learn another language.  If you're honest about that, then your choice will be simple and you'll be motivated to learn, no matter how how unfamilar or complex the new language is.

What happened to the fun of discovering new things? :)

Indian??... Perhaps Hindi or Urdu (mostly in Pakistan). India and Pakistan account for one in every five people in the world - about 20% of world population, and slightly more than all of China! (...although of course not all the people in India and Pakistan speak Hindi or Urdu.) If you're looking for common borrowed vocabulary, surely Farsi has many commonalities too.

I think linguists believe that Mongolian is related to Turkish. That country has been using the Cyrillic alphabet (as in Russia) since the 1940s. You will also find Mongolians in China, Kyrgyzstan, Kazakhstan and Russia.

I just had a look at Turkic Languages in Wikipedia. You may already know that Turkic languages from other countries include: Azeri, Turkmen, Uzbek, Kyrgyz, Kazakh, Uyghur (in China), and Tatar.

Looks like there are languages from at least 10 countries that you could choose from...
