Unfortunately, it appears that that you cannot, at least in the case of the first two husbands. If you had remarried after age 60, you would have been entitled to benefits on your prior deceased spouse's Social Security earnings record. But by reremarrying before age 60, according to the Social Security Handbook, you are not entitled to survivor's benefits unless "your subsequent marriage ends, whether by death, divorce, or annulment; or your marriage occurred after age 50 and you were entitled to benefits as a disabled widow(er) or disabled surviving divorced spouse." For details, check out this handbook from the Social Security Administration (SSA).
But you may be able to get spouse’s retirement benefits on your current husband's work record. For details, see this SSA webpage
