You can create variables and use them in a textbox. With var1 having a value of 437 and var2 a value of 28 the line
=var1 & 'h or ' & var2 & '%'
will show the text 437h or 28%
What you can't do is use different font sizes in one textbox. But you can use several textboxes one above the other so the line up nicely. You can put you calculations in variables. You can use chr(10) to insert line breaks.
=var1 & 'h or ' & chr(10) & var2 & '%'
