The answer depends on whether or not both unit 2 and 3 requires something from unit1 and/or if unit1 requires something from unit2 and/or unit3.

in short: impossible to provide a precise answer without more knowledge.

(no need to shout btw  :) )

was actually meant as
Quote
unit 2 and 3 requires something from unit1

then ...
Code: Pascal  [Select][+][-]
  1. unit unit1;
  2. interface
  3. implementation
  4. end.
  5.  

Code: Pascal  [Select][+][-]
  1. unit unit2;
  2. interface
  3. uses
  4.   unit1;  // in case something from unit1 is needed in this units interface section
  5. implementation
  6. uses
  7.   unit1; // in case something from unit1 is only needed in this units implementation section
  8. end.
  9.  

Code: Pascal  [Select][+][-]
  1. unit unit3;
  2. interface
  3. uses
  4.   unit1,  // in case something from unit1 is needed in this units interface section
  5.   unit2;
  6. implementation
  7.   unit1,  // in case something from unit1 is only needed in this units implementation section
  8. end.
  9.  
.. so that the answer to your first question becomes positive.
