Some lubricants would have the effect of replacing static friction with dynamic, if only because their bulk kept the solids offset from the static case. The general answer is no, however; the lubricant will present a new set of possible surface geometries in which the wetting energy is reduced, reactions to force changed, and of course the sliding friction case reactions reduced or changed as well.
Lubricants are characterized by their useful range for work; for example high-poly grease (2 million -mer where glycerin soap might be 30-250 -mer (i.e. that many carbons (on the case) in a chain)) is great for bicycle bearings and general machine use up to 5 meters per second; when trains need to go faster than that, you get to change wheel designs to run on oil (and different bearings, shifting the grease to duty on the suspension guide pins) so the lubricant isn't destroyed in seconds, in a manner very like a wool sweater on a drag-race wheel.1 Oil and powder lubricants degrade quickly at the common low-speed or high-load cases, though additives can help.

The basic idea of friction is to fitting the ups and downs of one surface into the ups and downs of other surface. Mostly, we cannot see ups and downs of surfaces with our naked eye as it is in molecular level. This lubricant's molecules goes and fits in to the ups and downs of our required surface and makes surface smoother so that these ups and downs of other surface cannot fit into the required surface. Thus lubricant reduces the friction.
ya, of course.

Lubricants reduce friction by replacing sliding friction with fluid friction.
the correction option is true :)

Its reduce by following ways By polishing the surface use lubricants by streamlining by air cushion by converting sliding friction in to rolling friction
Lubricating fluids have a sliding lattice structure which helps the atoms in the lattice to slide over each other and thus reduce the friction in the bodies in which they are applied. The relative sliding between the layers helps in lubrication.

Friction is phenomenon you see between two rough surfaces. A slippery liquid or lubricants when applied, coats over these rough surfaces creating a layer of the lubricant itself. Liquids like lubricants has very low viscosity, that is the sliding friction between two liquid layers, hence they easily slip over each other. In this way they help reduce friction.
Some ways to reduce the magnitude of friction are to use lubricants as they fill up in the irregularities and make the surface smoother, switch from sliding kinetic friction to rolling kinetic friction and by smooth surfaces that rub against each other.by polishing by streamlining in fluids . by ball bearing
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
you can use some anti-friction like lubricants (oil,gas).
