I have a 1996 Nissan Maxima Se, and Im looking to buy some rims but the bolt patterns is , 5X100/5X4.5 dual bolt pattern so my question is will this fit my car:??

nope, we have 5x114.3...

Yes it will fit. 5x4.5 is 5x114.3. 4.5" = 114.3mm.

also the offset is important as well as the width of the rim

look for a wheel with a 38-45mm offset and a 5x114.3 or 5.45 bolt pattern
