Romex wires in attic questions
I have been searching for days for a clear answer to this, if one already exists point me to it please because I can't find it.

I have an attic, it has one access point which requires moving a ladder in to position to climb up in to the attic.

In said attic there is romex wire which runs perpendicular to the joists of the ceiling from one side of the house (where the main is) to the other side of the house where the bedrooms are. Currently the wire is mainly just laying across the joists with a staple (loose staple, wire can still wiggle if you tug on it) every so often. Then each wire is stapled close to the box it goes into.

1.) Does this seems like it meets code?

2.)With in 7ft of the access do I need to install running boards and "substantial guard strips"

3.)would conduit be acceptable in lieu of running boards and guard strips?

4.)Past that 7ft is the current condition ok?

5.)If this was the case in your attic what would you do?

My head hurts from trying to understand the NEC and all the provisions, any help at all is soooooo very much appreciated...

Unless they plan to lay a floor down... 99% of the world will just live with it.
For the OCD type... they can get some boxes and covers and wirenuts and wire.
Route those circuits neatly off to the sides.

Loose staples is proper. If you pound them tight to hold the cable it is wrong as the cable be distorted.
You don't say how close they are to the access hole. The cable must be protected if they are closer than 6 feet to the edge of the hole.

320.23 In Accessible Attics.
Type AC cables in accessible attics or roof spaces shall be installed as specified in 320.23(A) and
(A) Where Run Across the Top of Floor Joists. Where run across the top of floor joists, or within 2.1
m (7 ft) of floor or floor joists across the face of rafters or studding, in attics and roof spaces that are
accessible, the cable shall be protected by substantial guard strips that are at least as high as the cable.
Where this space is not accessible by permanent stairs or ladders, protection shall only be required
within 1.8 m (6 ft) of the nearest edge of the scuttle hole or attic entrance.

Instead of re-running the cable you could add 2x2's next to the cables.

I'm Also for a 2x2, five minutes work and piece of mind

I'm also going to run wires through the attic.

is 2x2 the minimum thickness if nailing alongside cables, or can you use 1x2 furring strips too?

and after nailing strips next to cables, does the top need to be covered?

I like to use 2 X 4's instead, less likly to split when nailed.

And to the hijacker, no it does not need to be covered, but I for sure would not use 1X's, not enought height.
