If I am enrolled in Bachelor's degree taught in English, Can I in the future continue with Master's Degree taught in different language?
There is no need to repeat the degree. Just as non-English-speaking students can do graduate studies in the US after passing the Test of English as a Foreign Language (TOEFL), other countries also have language proficiency exams. For example, Germany has the "Test Deutsch als Fremdsprache" (TDAF). When you apply for your master's degree, they may require this test or something else (e.g., an interview) to prove your fluency. 

The more subtle point is that not all degrees are interchangeable. As my answer in this question points out, there may be a whole procedure to verify that your degree is compatible with the foreign one. This is unlikely to be an issue if you go to a reputable English-language school, but you may want to do further research before committing to this.
