mg2+ is positive and na+ is positive and positively charged ions repel?
F- is negatively charged and is attracted to the oppositely charged Na +

mg 2+ has an opposite charge too. it is a positive ion (and much more strongly attracted becasue it is smaller and has a large charge density than na?)

It doesnt,
Mg2+ is positively charged
Na+ is positively charged so it will repel with other positively charged things
F- is negatively charged and thus attracted to the na+
