I-452 write N/A or let spaces in blank issue

[Diana SA 2]

1- Hi, i am currently filling my application and in the form I-145 and affidavit of support they say currently on the USCIS instructions ''if an answer does not apply, let the space in blank'' but for the other forms they say to write NONE or N/A.

Now I am seeing people telling everyone to just put NONE or N/A in all the forms instead of let the space blank in the form that the USCIS tell you to let it blank. (I-145 and affidavit forms are the ones that USCIS says to let in blank on instructions )
Why that? What is the real solution and how should people do?

2-also, my husband is the petitioner and his 2 middle names doesn't fit in the space ( i am filling with adobe and 2d bar codes newest forms), people told me to put the first middle name and handwritte the second or the first middle name and the initial of the second. Is that what i should do?

3-should i fill one form to track online all the forms (I-145 and derivates /I-130) or one tracking form to each form or one tracking form for I-145 and one for I-130?

4- I currently live with my fiance in a house of a friend, we move to our place next month, is it alright if in my marriage ceritficate we have the friend adress and the other docs our new to be adress?

5- can i sign the printed and computer filled form with ink and there is no problem that my signature is my actual handwritten name?

Thanks for everyone that can help me, I am filling the forms alone and would appreciate it!

There are forms that specifically tells to leave the space blank if the answer is NONE or N/A. In my case, I just followed on what the instruction says. Hope this helps. By the way, you are applying for adjustment of status right? Did you mean to type I-485?

And did you got a good result my following the instructions and letting the spaces in blank? Cause someone told me a girl got rejected in her I-864 cause she didn't put N/A and let some answers in blank.....Yes that is what i meant lol, sorry, and thank you for your answer
