Silicone will work better.
Polyseamseal silicone caulk would be the best caulking to use with bathroom tile, if you're not going to pain the caulk. If you desire to paint the caulk, MAPEI latex caulk would be best to use with the bathroom tile.
No. Use the putty.
I use 100% silicon on the outside of the windows, and Alex ll caulk on inside.
None. Use Epoxy.
Use an exterior window caulk. If you plan to paint over it make sure it is "paintable" caulk. Run the bead of caulk using a caulking gun. You can smooth out the bead with your finger and clean up any residual caulk with a wet rag (this clean uo only works if the caulk is water based...check the tube to make sure it is....it's easier if it is) If you use silicone caulk you can't paint it and you cannot clean up any errors with a wet rag so unless you are real exact in applying the bead I would avoid this type of caulk.
You can use 3m's caulk remover and a sharp razor blade.

Instead of using any ordinary caulk, use Rubex Caulk. Rubex MS is a highly weather resistant and paintable caulk. It is very effective in sealing around our RV's vents AC's and corners. In addition, common applications include preparation for the Liquid EPDM Rubber around windows and door frames, flashing, and joint-filling.
I recommend that you caulk around the edges with transparent silicone caulking compound.
Caulk.
Not the greatest idea, when packing in the oakum and then pouring the lead and caulking it the hub could split wide open Your new caulking job will last longer if you remove the old caulk and any of its debris and make sure the area is dry before adding new caulk. You can use an old screwdriver to remove the old.
