Can you help me identify some toys from the 70's and 80's please?

1. This was a collection of small humanoid figures in clear plastic with different coloured shiny insides. They were articulated but you could change their arms for weapons.

2. What looked like a big rifle except the red end was a directional microphone.

3. An orange/yellow wall down which a ball bearing travelled. You had to build a blue tower before a timer ran out and the ball bearing knocked over the tower.

4. Fighting robots in a boxing ring - NOT "Sock 'em, Rock 'em" or "Raving Bonkers".

5. An airplane that sat on top of a blue base. You filled it with parachutes. As the base rotated beneath it, you lined up the sights and dropped the parachutes into the dips in the rotating base. You could move the plane in and out to line up with drop points.

6. A blue tray with white 'rockers'. You filled the blue tray with marbles, blue, red and yellow. There were cards with different patterns of blue, red and yellow 3x3 squares. As marbles fell to the bottom, the cards were filled up.

Thanking you in anticipation!
