The platoon is composed of several different units, so each of those are separate, scoring units. Even if they only counted as a single unit, a single unit may still capture multiple objectives (see the rulebook
FAQ).
And in annihilation - does each part of the platoon give 1 point, or only the whole platoon destroyed counts as 1 point?
They are separate units, so each one counts as a kill point (much like a dedicated transport is also a kill point). It's one reason why you would make use of the Combined Squads rule: if you combine all of those Infantry squads, you shave off a few potential kill points from the army.
2. I noticed that heavy weapons teams are fielder either on one 60mm base or on two bases - 40mm+25mm? Are both options allowed in official games?
Older Imperial Guard models had the loader and firer mounted on separate bases because their rules allowed it to happen. The newer
IG codex does not contain any rules allowing for heavy weapons teams to be split like that, so they must be mounted on the same base and are treated as a single, two-wound model.
IG codex, p29.
One common solution for this is to take the separately-based models and glue (or magnetise) the bases onto a larger 60mm base. Easy.
