2. Choice	Selectbox(60 item)	Selectbox(30 item)	Yes/No Question
3. Choice	Selectbox(60 item)	Selectbox(30 item)	Yes/No Question

is it possible to do that?

A mixture of question types isn't possible at Limesurvey. You can find a list of supported question types here: docs.limesurvey.org/Question+types&struc...tions+for+LimeSurvey

For the first question a dual scale (dropdown) question type might do the trick.

To show answers selected at a previous question have a look at the question attribute "array_filter": docs.limesurvey.org/Advanced+question+se...eSurvey#array_filter
