You may well get 3x number 7 with the new strut bearing you purchase. This is the best way to obtain them, but they are not of a rare nature. I’ll see if I can find a number though.
Number 5 is the nut on top of the actual strut piston. I have reused the old, but many will (rightly) state they replace with new.
Again, will need to look for the code (may not be one, as part of the strut).
Tip: I use about 3-4 washers under this nut, so the nut is high enough out of the bearing to get decent purchase for ring spanner. All depends on the brand of strut bearing you have, but they all seem to have the nut quite low, and therefore difficult to get anything but a socket onto (and you may need to have a hex key to hold the actual piston at the top, so thus the use of a ring spanner).
There are a few posts on here for this task, including one from me I think…….
