I tried like this but it's showing server's language:

PHP Code:

public client_putinserver(id) {
    new lang_id, lang[3];

    get_user_info(id, "lang", lang, charsmax(lang));
        
    lang_id = get_lang_id(lang);
        
    get_lang(lang_id, lang);
}

get_lang_id(lang[])
{
    new tLang[3], g_langNum;
    
    for (new i = 0; i < g_langNum; i++)
    {
        get_lang(i, tLang)
        if (equali(tLang, lang))
            return i
    }

    return 0
}

Why are you doing all of that looping when get_user_info already returns what you need? Delete everything after the third line of code.

Because it's always showing DE but my language is set to EN

The multilingual plugin uses set_user_info(id, "lang") to set the player's language, so you should be able to get it with get_user_info(id, "lang").
