Greetings to you and your Thai friend, bhante!
1. Are you a Buddhist?
2. Are you interested in Buddhism because of the meditation?
I see meditation as a means to an end.... so it would be more accurate to say I'm interested in meditation because of Buddhism!
If you are a Buddhist ;
3. Do you see ‘ meditation’ as most relevant to the Dhamma practice rather than other social meritorious activities? why?
Meritorious activities are a good support and basis for practice, but meditation and Dhamma study (preferably a combination of both) are required in order to attain stream-entry. "Social meritorious activities" existed before the Buddha, but these did not, in themselves, lead to enlightenment. Heavenly realms, yes... just not enlightenment.
4. Do you think to give material requisites to monks (Dana) can generate merits across Samsara (transferring to next lives)?
and how this activity is important to you?
Yes, and it is important though unfortunately as Western Buddhists, our opportunities to make regular offerings to the Sangha may be limited by our lack of proximity.
