Don't think what you're after is possible using a non-proportional font like Calibri because width is based on the characters used not the character count.
an example with same number of characters:
GALA - XX, XXXXXX INDUSTRIAL PARK, PLOT XXX/1, XXXXXX MIDC, XXXX MUMBAI - XXXX05.
GALA - II, IIIIII INDUSTRIAL PARK, PLOT III/1, IIIIII MIDC, IIII MUMBAI - IIII05.

Are you interested in a macro solution using a fixed width font like "Courier New" ?
same examples:


GALA - XX, XXXXXX INDUSTRIAL PARK, PLOT XXX/1, XXXXXX MIDC, XXXX MUMBAI - XXXX05.
GALA - II, IIIIII INDUSTRIAL PARK, PLOT III/1, IIIIII MIDC, IIII MUMBAI - IIII05.

also, is the period and space at the end of the address really necessary ?

what about the vertical alignment of the sentences?

the letter 'G' from word GALA and letter 'C' from the word contact must coincide.
and same with the right side that below no. 5 from pin code the last letter of GST no. must coincide.
