In this case, because 'другими студентами' is the instrumental plural, the ending takes 'ими'.
Not exactly. You must take out of the verb its ending ('ют'), than add the suffix ('ющ'). In general, there are 7 suffixes of participles. Shall I give them here?
Yes " Я встречаю Пушкина" , but 'Я встречаюсь с Пушкиным' 'ым' - is the ending of noun. It depends on case, declension, gender(he, she, it), number(sing., plural).
