For Q3, you need to know the different types of reactions involving acids or bases or both; which reacts with which and the types of products formed.
For Q4 and Q5, you need to know which salts are soluble and which salts are insoluble (there is a list which you must learn in the syllabus). One thing to note is that salts of alkali (Gp I) metals are always soluble in water.
Additionally, you must know what the techniques of titration, precipitation and filtration are used for and in which type of situations.
