I would think that Lady Davina, Lady Rose, Lady Frederick and Lady Gabriella will not wear tiaras as they're too far from the throne (great-grandchildren (and spouse). Laura Lopes definitely won't. Zara might as the granddaughter of a sovereign even though she's not titled; same for Lady Sarah. The Countesses of Ulster and St. Andrews might be in tiaras but maybe not as their husbands' titles are courtesy titles only.
I noticed you left Princess Beatrice and Princess Eugenie off your list. I would think one of them would wear their mother's tiara and the other possibly the Lotus or the Halo, with Lady Louise, if she's over 18, wearing the other. Sarah York would only be there if by some slim chance she and Andrew had remarried.
And many of these tiaras would be worn with coronets inside them after the actual crowning; either those of duchesses, or daughter (Anne) and granddaughters of a sovereign (Princesses Beatrice and Eugenie, Louise, Zara, and Lady Sarah.)
