@3hfh+16gI2n6C If you are still employed at Honeywell you can only do a rollover or distribution of the Employer Matching part of the account.
If you are no longer at Honeywell you can do a rollover or distribution of the entire amount. If you DO roll over the 401k into an IRA and you WERE eligible for the Rule of 55 then you lose that eligibility because it only applies to a 401k and not to an IRA. You would then need to use Rule 72T for early unpenalized withdrawals.
If Honeywell were to go bankrupt your 401k is still safe. Your pension (if you have one) is a different story and that would depend on the amount of funding and the federal pension insurance.
As far as the OP's question, I know that we get to VOTE the equivalent shares and you ARE considered a shareholder, but I do not know if they count for the Class Action. Another thing to consider is if the shares where employer match shares or shares you purchased in the 401k fund yourself (where any company misrepresentation would come into play).
