Yes, you can use two particles at the same time, but not always. Like Lesha and 형주신 said, it doesn't work in your example. -만 (only) + -은/는 (topic) 너의 빛을 받아도 내 그림자만은 얼어 가 Even if I receive your light, my shadow only keeps freezing (I couldn't find a casual sentence for this combination so I think it's rather poetic) -만 (only) + -이/가 (subject) 너만이 날 웃게 할 수 있어 Only you can make me laugh -만 (only) + -을/를 (object) 너만을 사랑해 I only love you -만 (only) + -의 (possessive) 넌 나만의 친구 You're only my friend (not anyone else's) -에게 (to) + -만 (only) 나에게만 말해 줘 Tell it to me only (Note that this order can't be changed, it has to be -에게만 not -만에게) -에서 (in) + -도 (too) 집에서도 할 수 있어요 You can do it at home too -(으)로 (means) + -도 (too) 음식은 눈으로도 즐길 수 있어요 Food can be enjoyed with the eyes too There is also -와는, -보다는, -보다도, -까지도, -에게는, ... Too many to list them all but remember that you can't combine -은/는, -이/가, -을/를 and -도 with each other.

Lesha is right :)

Hi, if you want to say 'I am a student too," (as in someone says that they are a student, and you reply that you also are a student), you would just say '나도 학생이에요.'
