Metals are good electrical and thermal conductors.
Well it could if your foil was thick enough to act as a thermal mass but as a foil, no. generally aluminium acts as a reflector to direct thermal energy - eg reflecting sunlight. As such under a laminate floor it would be very ineffective.
because it conducts heat very well.
The thermal conductivity of aluminium is 237 W/m.K.

Rigid insulation by DOW makes many different types of insulation, most have a foil side which should be glued to the concrete while the colored side with logos on it will face out ready for walls to be framed and sheetrock to be hung.
High melting point, Hard, Rigid, Strong, Brittle, Electrical and Thermal Insulators.
Tin foil is not a thermal insulator and so is irrelevant to the question.Bubble wrap is a better insulator at low temperatures but as the temperature increases bubble wrap will simply melt and provide no insulation at all.
It depends on the thickness of the two materials, typically Foil will keep things much colder because of its very high thermal conductivity.
answ2. Heat is not 'attracted' 'repelled' by anything.Polished aluminum foil will, and thus is a thermal insulator.Aluminium metal itself is a good conductor of heat.It will reflect the sunlight and retain the heat.
