Irony metal “pestle” found outside—is it a metalworking tool?

Found in a recently purchased house. Red tube like object with a twist handle at top. Looks fairly old.

What is this silver ball on my ceiling?

Glass 'jar' with a ring of holes around the base, about 20cm round and looks to be handmade but no idea what it is for!

Small plastic piece, length of a pinky, the red part is flexible like a plastic flag. White part has one sticky side. Fell out of a window when we opened it.

Double handle wood and metal post tool, what is it?

Just bought a house, found this hidden inside the front bushes. Screws in a wooden ball, looks like a mace. What was/is this used for?

I have only been living here less than a month. Previous owner was in his 90's and moved out to receive care from a family member. Quiet neighborhood. Eastern Canada. Anything helps!

Metal mechanical thing with crank and funnel in truck bed

Medium sized truck, driving in Missouri. Couldn’t identify via reverse image search.

Metal rod, about 8in long with 3 loops of similar size one at each end and one directly center with a thumbscrew in the middle hole, feels like hollow aluminum

12”x12”x4” cast iron metal object with no other markings found on a lathe in the fabrication shop of a 30+ year old book binding company.

Steel tool(?) ~34mm long made from 1mm thick wire with a delta shaped back end and two "legs" that are crossing, which end in ~1.5mm ball "feet". The legs are of different lengths, and have been stamped flat in the middle of the item. The legs move only slightly with moderate finger pressure before

For context I found this inside a lens cap for a Fuji Finepix X100, which I had covered in tape to keep the item from getting lost. It was accompanied by random wood and machine screws, none of which belonged to the camera, so I have my doubts that it's camera related.
