Thanks for corrections on last two passages. Most of my problems were the same as Graces´s so in addressing hers you have solved mine.

In case my comment in last passage re: hvorirtveggju misleads you, I submit a corrected comment:
þing með Áskatli goða. Eru hér nú hvorirtveggju (pronoun acting as adjective, see hvárrtveggi, Z1, here weak fem nom plural form agreeing with vottarnir) vottarnir þeir er við voru
(the) thing-district with priest-chieftain Áskel (ie to be his liegeman, follower, see under þing, Z3).Here are now both (see hvárrtveggi, Z1) those witnesses who were with (him) (ie present)
